(qIV)
**A fast, GPU-accelerated image viewer for Windows.**

Direct2D, WIC and native Win32. One portable sub-10 MB EXE — no installer, no
telemetry, no background service.
Culls a photo shoot in one pass — **[one keystroke per picture](#cull-mode)**, keep or
reject, and the rejects move together at the end. Nothing touches the disk until you say so.
Drives other copies of itself over plain TCP, mirrors one screen to many, and has
**[an Android app](#qiv-remote--the-android-app)** that turns any phone or tablet into a
remote control, a second screen, or a **photo frame your PC drives** — as many of them at
once as you have devices lying around.

**Drive the viewer**
Next / previous, first / last. Slideshow with its interval, pause, loop and shuffle.
Zoom, rotate, flip. All five view modes. Colour effects. Fullscreen, always-on-top,
panels and the on-image overlay.
**Jump anywhere**
The viewer's folder history comes down to the phone — tap a folder and the desktop goes
there.
|
**Presentation mode**
The current picture and two large next/previous buttons, sized to press without looking.
Built for talking to a room rather than staring at a phone.
**Follow the desktop**
Bind the connection and the preview keeps itself up to date — when someone changes the
picture at the PC, your phone shows it.
|
|
**As many PCs as you like**
Each saved machine keeps its own address, port and optional password. Tap one to connect.
|
**Demo mode**
Every screen runs against a viewer that does not exist, so you can see the whole app
before installing anything or opening a port.

### A private network, and nothing else
The app talks only to the computer whose address you type. There is **no account, no
cloud, no analytics, no advertising**, and nothing is ever sent to the developer — there
is no back end to send it to.
When your PC requires a password it is verified by challenge–response, so **the password
itself never crosses the network**. Off the loopback the connection is TLS with a pinned
certificate, and qIV's own AllowList (`F9`) still decides who may connect at all.
Passwords you choose to save stay in app-private storage on the phone.
### Requirements
It is a companion app and does nothing on its own — the same way a TV remote does nothing
without the TV. You need **QuickImageViewer running on a Windows PC with its Local Server
enabled** (`F9` in qIV), and the phone on the same network. The app's About screen walks
through the setup.
