Instant Booth Gallery von cndr

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 and a see-all grid, with full keyboard control — arrow keys, scroll or +/− to zoom, drag to pan, 0/1 to fit or actual size, Home/End, G for the grid, and ? for an in-viewer list of every shortcut. All optional, all toggleable from the popup.
• Shows an optional on-page progress badge ("Loading gallery 7 / 12") while the gallery loads, and hides it once every picture is in.

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.
