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, 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
