Image Gallery Plus

A feature-rich extension that brings you the best image browsing experience in VS Code, especially for remote / cloud development.

This is a maintained fork of geriyoco/vscode-image-gallery, which has been inactive since 2024.

Highlights

Thumbnail Compression: Generates compressed thumbnails on the backend using WebAssembly (wasm-vips), dramatically reducing bandwidth in Remote SSH / WSL / Containers sessions. Configurable size, quality, and output format, with a persistent disk cache.
Gallery View: Collapsible grid of all images in the selected folder and its sub-folders.
Lazy Loading: Images load on-demand as you scroll (tested on 10k+ images).
Live Refresh: Automatically updates the view when images are modified, added, or deleted.
Glob Filter: Filter images by glob patterns (e.g. *.png, **/icons/*) directly from the toolbar.
Adjustable Thumbnails: Resize thumbnail grid with a slider in the toolbar.
Theme Integration: Fully respects your VS Code color theme.
