EPosters

E-posters on a touchscreen. Two modes: Kiosk (a thumbnail grid; a tap opens the poster full screen) and Strip (swiping moves from poster to poster, endlessly, with search by name). Posters (PDF, PNG, JPG) come in by USB stick or over the web, and the app never interrupts what is on screen.

Needs an activation code, which you type on the PC itself: without it the server stays locked. It then shows the receivers' codes (one per device). It installs an icon next to the clock that opens the administration page. Devices on the same network find it by themselves. The installer opens port 8780 in the firewall, on private networks only. It is not digitally signed: Windows may ask for confirmation.

It connects to a poster with the short code and shows Kiosk and Strip, with pinch zoom. It counts as one device in the pack, just like an Android receiver. It starts with Windows, doesn't let the PC fall asleep and brings an on-screen keyboard. To leave the kiosk, press the top-left corner for 1.5 seconds. It needs Microsoft Edge WebView2, which already comes with Windows 10/11. It is not digitally signed: Windows may ask for confirmation.
What's new by version
Android app, Windows server and player. Each version has its own address: eposters.html#v1.0.30
v1.0.30
Server v1.3.6 · 6 Nov 2026Video in posters: it accepts MP4 files (H.264) through the dashboard, the library, the inbox and the client's link, with upload in 16 MB chunks and a configurable limit. The apps and the player play them muted by default, and so does the viewer in the browser. The dashboard shows the ▶, the duration and the orientation, and warns when the video is H.265. The frame only exists on the grid tiles (the opened poster, the Strip and the presentation don't have it) and the content is clipped by the rounded corners.
Windows Player v1.0.5 · 6 Nov 2026Refined frame: the poster is clipped by the frame's rounded corners. When you open a poster full screen (in Kiosk and in Strip) there is no frame: the frame only exists on the grid tiles.
App v1.0.30 · 6 Nov 2026Refined frame: the poster is clipped by the frame's rounded corners and no longer spills out of it. When you open a poster full screen (in Kiosk, in Strip and for videos) there is no frame: the poster fills the whole screen. The frame only exists on the grid tiles.
Server v1.3.5 · 5 Nov 2026Event branding organised in blocks (event, logo, background, rotation and frame), each with “All posters” or “Each poster”. The frame becomes the card of the grid, with a thickness of up to 120; in Polaroid the file name goes inside the bottom margin. The inbox shows thumbnails and opens each file in “View”. The client project creates itself when you save the event name. There is a space meter and a 7-day recycle bin to undo a delete. Thick frames only reach the apps that know how to draw them.
App v1.0.29 · 5 Nov 2026Frame as a card: each poster in the grid is the frame itself (line, double, shadow, Polaroid or rounded), with a thickness of up to 120. In Polaroid the file name goes inside the bottom margin, with the minimum of space.
Windows Player v1.0.4 · 5 Nov 2026Frame as a card in the grid, with the file name inside the Polaroid and a thickness of up to 120.
Server v1.3.4 · 5 Nov 2026Screen rotation (0°, 90°, 180° and 270°) per screen and per poster, and poster frame (line, double, shadow, polaroid and rounded), with a warning when the screen doesn't match the poster. The dashboard shows whether each poster is portrait or landscape and lets you filter by orientation. Search by PDF text also reaches the screens (magnifier), there are Library and Settings tabs in the dashboard and the codes get their hyphen automatically. The option to also read the text of images (OCR) exists only on the online server and comes switched off.
App v1.0.28 · 5 Nov 2026Search by PDF text in the Kiosk and Strip magnifier (with server 1.3.4): it shows the name, the page and the excerpt with the words highlighted, and opens the PDF at the right page. Remote-only use: the MENU key opens Settings and the “New version” notice takes focus and stays until it is closed.
Windows Player v1.0.3 · 5 Nov 2026Search by PDF text in the Kiosk and Strip magnifier (with server 1.3.4), with the result at the right page.
App v1.0.27 · 5 Nov 2026Video in posters: plays MP4 files (H.264), muted by default. In the Strip the video starts by itself on arrival and stops on leaving. Video uploads to the server arrive with a later server version.
App v1.0.26 · 5 Nov 2026Software screen rotation (0°, 90°, 180° and 270°) in Settings, for portrait TVs connected to boxes that don't rotate the screen. The receiver code now gets its hyphen automatically and accepts being pasted. The poster frame is made ready.
App v1.0.25 · 5 Nov 2026Own on-screen keyboard, for boxes connected to touch monitors where Android's keyboard doesn't appear. It opens by itself when needed (or with the ⌨ button next to each field), with big keys and a keyboard with only the characters valid for the connection code.
Windows Player v1.0.2 · 5 Nov 2026Video (MP4) in posters, muted by default, with pause and volume.
Windows Player v1.0.1 · 5 Nov 2026Software screen rotation (0°, 90°, 180° and 270°) in Settings, the automatic hyphen in the receiver code and the poster frame made ready.
App v1.0.24 · 5 Nov 2026Poster background: the app applies the colour chosen in the dashboard behind the poster, in Kiosk and Strip, and adjusts the text and icons by itself so they read well. It changes live and, without a network, keeps the last value.
Server v1.3.3 · 5 Nov 2026The PDF text is read by itself (at startup and on each new file) and the search finds words and phrases, with the status “Text read in 6 of 6 PDFs”. The top bar is always visible, with no page jumps, and the notices are compact and close by themselves. Add file asks “From the computer” or “From the library”, and deleting a poster is done on the card itself. Less information in view: sections collapsed by default and menus per task. Nothing is deleted without confirmation, on the server too, and deleting the library (all of it or the chosen items) asks for stronger confirmation.
Server v1.3.2 · 5 Nov 2026Event dashboard: a new home page with the status of each poster and each screen, in light or dark mode and working well on the phone. The posters' background colour is chosen per poster or for all at once, and reaches the screens live. The usual panel stays under “More”.
Server v1.3.1 · 5 Nov 2026Client inbox: each project gets an inbox where the client drops all the files at once, without choosing the poster. Nothing goes to the screen until you sort it, with “Put here”. In projects that already existed it comes switched off; turn it on under “More → Projects”.
Server v1.3.0 · 5 Nov 2026Search inside posters: in the viewer, find a poster by the words that are inside the PDF, not only by name, and it opens straight at the right page.
Windows Player v1.0.0 · 5 Nov 2026New: the receiver for a mini PC with a touch television. It connects with the short code, shows Kiosk and Strip with pinch zoom, starts with Windows and reconnects by itself. It counts as one device in the pack.
App v1.0.23 · 5 Nov 2026The dashboard's QR opens a page with Open in the app or View in the browser. The app connects to the poster by itself, by link or by short code, after you confirm “Connect this receiver?”.
Server v1.2.9 · 5 Nov 2026Web viewer: see the posters in the browser of any device (phone, iPhone, tablet, PC and TV with the remote), read-only, with grid or strip, PDF, zoom, search and automatic refresh. The QR carries a link that changes every 3 hours and each session lasts 3 hours (“Session ended: scan the QR again”); the app's key doesn't change. On the TV there is an automatic presentation. The viewer doesn't count as a device.
App v1.0.22 · 4 Nov 2026Connecting to a poster step by step: Settings opens with the address, the connection code, Connect, receive the posters and done, with a tick on each step. After connecting with the code, the app waits for the first sync and goes back to the posters by itself. The “There are no posters yet” screen explains the two steps and the button is now “Connect with a code”.
Server v1.2.8 · 4 Nov 2026Under General, Organise everything: all posters side by side, each with its own panel to drop or import files from the PC, drag from the library (a copy is made, or “Copy to…”), reorder and remove, without changing poster. In each poster's menu, Connect a receiver guides you in 5 numbered steps (create poster, add files, generate code, type it on the receiver, receiver connected) and moves on by itself when each step is done.
App v1.0.21 · 4 Nov 2026Connect without typing the read key: in Settings → Server, type the Connection code (6 characters, generated in the server dashboard) and press Connect; the app receives the poster and the key by itself. Designed for receivers without a camera (TV box, remote only). The long key and the QR keep working. Files sorted in the “Organise” panel appear in the right order, without the leading number in the title.
Server v1.2.7 · 4 Nov 2026On the poster, the new Organise panel: import from the PC (button or drag), drag media from the library to the poster (a copy is made: deleting from the library doesn't break it), reorder by dragging and remove. Under “Connection and keys” you generate the short connection code (validity of your choice, regenerate or revoke).
v1.0.20 · 3 Nov 2026Kiosk: search becomes a discreet magnifier in the top-right corner. Tapping opens the bar (with keyboard), the X clears and closes, and it closes by itself when the screen is idle.

Como funciona

KioskA grid of thumbnails. Tapping opens the poster full screen; the ✕ goes back to the grid. A multi-page PDF is paged through by swiping.
StripThe 1st poster full screen; swiping moves to the next, in an endless loop. Search-by-name and home buttons.
USB stickCreate an EPOSTERS folder on the stick and plug it into the device: what is new comes in and what has the same name is replaced. A config.json sets up several devices at once.
WebUpload, replace and delete posters on a page, per channel; devices receive them within seconds, without anyone touching them. It works with the PC server (local network) or with your online space.
No interruptionsWithout a network, it uses what it already has. An update never changes the poster that is on screen.
Client projectsIn the administration you create a project, choose the eposters and copy one link for the client. They drop the posters straight onto the screens, replace and delete only what they uploaded themselves; what you uploaded stays protected. No approval, no need for you to stand guard.
Client logoUpload a client's logo in the administration: it appears at the top of the grid (Kiosk) on that channel's devices, within seconds.
Remote statusThe administration shows each device: whether it is up to date, what it is showing, the battery and how long ago it last reported. Useful with several spread around.
Adapts to the screenThe tiles fill the screen (few posters = big ones) and the size of the text and buttons adjusts itself to large screens; you can choose the size in Settings.
Receivers with a codeEach device connects to the server with its own code: it is tied to that device, and if one breaks down the seat is freed and the code is used on another. A server whose contract has ended or is blocked only affects its own receivers.
Rename postersGot the name wrong? Change it in the administration: devices that already used it keep seeing the poster without anyone touching them.
Space libraryUpload each poster just once and it appears on all the space's screens; on each screen you choose it on the grid and search by file name (ignoring accents and capitals). Turn it on in the dashboard whenever you like: with it off, nothing changes.
Kiosk modeStarts by itself, screen always on, no system bars, optional PIN in Settings, pinch zoom.
