A JupyterLab 4 extension that makes the built-in image viewer interactive. Images open fitted to the panel just like the stock viewer, then you can zoom with the wheel, pan by dragging, and step through a folder of images with the arrow keys - all in a single viewer tab.

## Features

- **Fit to screen** - every image opens scaled to fit the panel (same result as the stock viewer), and reset returns to that fit
- **Wheel zoom** - scroll to zoom in and out, anchored at the cursor; zoom out as far as you like
- **Drag to pan** - hold and drag to move around a zoomed-in image
- **Toolbar controls** - zoom in, zoom out, and reset-to-fit buttons on the viewer toolbar
- **Arrow-key navigation** - Left and Right open the previous and next image in the same folder, advancing within one viewer instead of opening new tabs

## Requirements

- JupyterLab >= 4.0.0

## Install

To install the extension, execute:

```bash
pip install jupyterlab_advanced_image_viewer_extension
```

## Uninstall

To remove the extension, execute:

```bash
pip uninstall jupyterlab_advanced_image_viewer_extension
```
