Imagus

This extension is designed to supplement the image features that are missing by default (I assume), or to provide simple yet useful functionalities. **Hover Zoom** Enlarges thumbnails and linked images (even linked thumbnails) in a pop-up that appears only when the mouse hovers over them. **Viewer** Replaces the browser's default image resizer with a more customizable version. For instance, you can set the initial size mode or completely disable resizing. **Tools** **Shortcuts** - Open Image - Send Image to... **Filters** This is a set of rules that help the extension locate larger images. These rules are based on regular expressions, JavaScript, and some HTML. **Gallery** This functions like a bookmark for images. It stores only the image address with a thumbnail, and if possible, just one or two source links. The "source" refers to the address of the page where you viewed the image, while the "target" is the linked address (if it differs from the zoomed image address). When opening an image or hovering over it, press the shortcut (default: G) to add it to the list without any prompts. Shift + G will prompt for a tag. To remove an image from the list: Ctrl + right-click the thumbnail cell or Ctrl + click to select and remove some via the button list. Shift + right-click a cell to edit its tag. **Permissions** In the permissions section, you can specify which sites the extension is allowed to work on. You can also block only certain filter rules.

Imagus is a browser extension that enhances image functionality by enlarging thumbnails and linked images on hover, offering a customizable image viewer. It also supports image collections, rulesets for finding larger images, and site permission management.
