Instant Gallery Viewer for Booth

Loads every booth.pm gallery image up front and adds an instant zoomable viewer with a see-all grid. No more click-then-wait.

Instant Gallery Viewer for Booth makes the image gallery on booth.pm item pages load and browse instantly. booth.pm item-page galleries only truly load the first image. Every other slide is fetched the moment you click its thumbnail, so you wait on a spinner each time. This extension fixes that: • Pre-connects to booth's image CDN the instant the page starts loading. • Pre-loads every gallery image up front, so clicking a thumbnail is instant. • Optionally shows full-resolution originals, and warms them on hover. • Adds an instant, zoomable full-screen viewer, a see-all grid, and keyboard navigation (← / →). All optional, all toggleable from the popup. Everything runs locally in your browser and only on booth.pm item pages. No data is collected, transmitted, sold, or shared. No analytics, no accounts. Made for fun in my spare time and offered free, as-is. Bug reports and questions are welcome at cndrcndrcndr@proton.me. I read everything, though I can't always reply. If it saves you time, there's an optional tip jar in the popup, and every feature is free either way. Not affiliated with, endorsed by, or sponsored by pixiv Inc. or BOOTH.
