Image Grab

A Chrome extension (Manifest V3) that shows every image (and video file) on a page in a clean, Atlas-style gallery so you can pick the ones you want and download them.

Install

1. Open chrome://extensions
2. Turn on Developer mode (top right)
3. Click Load unpacked and select this folder (or Reload if it's already installed)
4. Pin the extension, open any page and click its icon

Using it

Clicking the icon opens the gallery as an overlay on the current page (a white panel, 95% wide and 92% tall) and scans the page. Close it with the ✕, Esc, clicking outside, or clicking the icon again. On pages Chrome doesn't let extensions touch (like chrome:// pages) it opens in a tab instead and explains why.

• Gallery: justified rows, each image at its real proportions, dimensions underneath.
• Videos: video files on the page (<video> sources and links to .mp4, .webm, .mov…) show as tiles with their length in the corner and play silently while you hover. Streamed videos (Instagram, TikTok, YouTube, Vimeo, X…) have no single file to download, so only their cover image appears.
• Click an image to open it full size (it springs out of its tile). Use ← → to browse, Esc or click to close. Videos play with sound and player controls; clicking the video plays or pauses it, so close with the background, ✕ or Esc.
• Select images (top right; it says Select videos when only videos are showing, and Select for a mix) switches to selection mode: click to tick images, Shift-click for a range, ⌘A for all. The bottom bar then lets you Download or Copy links. Cancel or Esc leaves selection mode.
• Downloads go to Downloads/Image Grab/<site>/, with live progress in the corner toast (hover the ⓘ for per-file status).
• Filters (top): type (Images, Videos or a single format) and minimum size (defaults to 300 px + to hide icons).
• Crawl site: follows links from the page and adds images from each page it visits.
• ⋯ menu: scan again, scroll the page to load lazy images, select all, clear.
• Bottom corners: shuffle, zoom out / in (also - / +), sort.

Add to Atlas

Select images, then Add to Atlas (in the selection bar, or in the full-size preview). Atlas downloads each image into its Inbox; the corner toast shows progress, and Show in Atlas opens the Inbox.

Atlas refuses requests from browsers, so the extension goes through a small local helper in atlas-bridge/:

• Set up once: sh atlas-bridge/install.sh (needs python3). Remove with sh atlas-bridge/install.sh --uninstall.
• Store users without this folder: curl -fsSL https://raw.githubusercontent.com/Push3in/Image-Grab/main/atlas-bridge/get.sh | sh (the setup page store/atlas-setup.html explains it; the gallery's More menu links to it until the helper is installed).
• The helper reads your Atlas key from the library's .mcp-token file each time, so no key is stored in the extension. If Atlas isn't running it opens it in the background.
• Only this extension may use the helper: the installer reads the extension's ID from each browser. For a copy installed from the Chrome Web Store, run sh atlas-bridge/install.sh --id <store id>.
• The Add to Atlas buttons only appear when the helper is installed.
• Images embedded directly in the page (data: URLs) can't be sent, since Atlas fetches by web address.

Publishing

store/listing.md has everything for the Chrome Web Store dashboard (description, permission justifications, privacy answers), store/screenshots/ the 1280×800 screenshots, and store/privacy-policy.html the privacy policy to host. Upload dist/image-grab-<version>.zip. To rebuild it after changes, bump the version in manifest.json and zip manifest.json, the .js/.html/.css files and icons/.
