jupyterlab_advanced_image_viewer_extension

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.

Advanced image viewer

The viewer toolbar adds zoom in / out / fit controls and a help link that lists every keybinding.

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 the image at any zoom; the image can touch a viewport border but never leave it, the grab cursor is always available, and Fit recenters
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, in the order the file browser lists them, advancing within one viewer instead of opening new tabs
Copy to clipboard - right-click a raster image (PNG/JPG/…) and choose "Copy to Clipboard" to copy it as PNG to the system clipboard
Refresh - a toolbar refresh button reloads the image from disk, the same control the HTML viewer provides
WebP support - .webp files open in the image viewer with every feature above; stock JupyterLab opens them in the text editor
