Imagus

Enlarge thumbnails, preview full-size images, play hover videos, and page through galleries on mouseover with zero setup.

Imagus enlarges image thumbnails and previews full-resolution photos, multi-image galleries, and video streams whenever you hover your mouse cursor over a thumbnail or media link. Designed for fast, everyday browsing, the extension automatically detects scaled-down preview images and loads the original uncropped source file in a clean floating viewfinder frame without leaving the current page. KEY FEATURES Instant Full-Resolution Preview: Hover over any thumbnail or direct media link to inspect the full-size image or video stream immediately. Multi-Image Gallery Navigation: Step through multi-photo posts and image albums directly inside the hover preview using your mouse wheel or the left and right arrow keys. Built-In Viewfinder Controls: Press Z to enter interactive full-zoom mode, R to rotate the image 90 degrees, H or V to flip horizontally or vertically, S to save the media file to your computer, C to copy the media address, and O to open the file in a new tab. Customizable Trigger Behavior: Configure your preferred hover delay in milliseconds, require a modifier key (Alt, Ctrl, or Shift) before activating the preview, dim the background page, or mute hover videos by default. Per-Domain Controls and Custom Rules: Exclude specific websites whenever needed and import or export custom URL resolution rules in JSON format. PRIVACY All image resolution and preview rendering happens locally inside your browser. Imagus does not collect, transmit, or store personal data, browsing history, or analytics on external servers.
