Alt Image Zoom Modal

Chrome ExtensionJavaScriptImage ToolsIndexedDBProductivity

Alt Image Zoom Modal is an unpacked Chrome extension for working with images directly from any webpage. It adds a lightweight inspection layer on top of the browser: alt-click an image, open it in a modal, zoom in, pan around, move through nearby page images, and save the ones worth keeping.

How it works

The extension collects page images and videos into a thumbnail carousel, then presents the active image in a focused viewer with fit-to-stage sizing, wheel zoom, button zoom, drag panning, double-click reset, and keyboard navigation. A grid view makes it quick to jump between candidates without returning to the source page.

The saving workflow is built for repeated image review:

  • Save the active image into extension-owned folders.
  • Bulk-select page images from a thumbnail grid.
  • Download one image directly or multiple images as a ZIP.
  • Store image bytes in IndexedDB so saved images remain available after leaving the original page.
  • De-dupe saved images within a folder using a SHA-256 content hash.
  • Open saved folders in a full-tab viewer with the same pan-and-zoom interaction.
