Image Max URL

By: qsniyg
Finds larger/original versions of images (supporting 10,000+ websites), including a powerful media popup feature

Features & Capabilities

Image Max URL helps you find and download larger or original versions of images and videos across roughly 10k sites using ~6k site-specific rules. It supports many generic engines (including Wordpress), so it works on most sites even if not explicitly listed. The extension includes a highly configurable image popup (Shift+Alt+i by default), hover-based access, or a right-click menu item.

Key features include automatic gallery detection with popup browsing, optional image replacement to larger versions, and batch downloads of selected media. It also emphasizes privacy, with no tracking code, and offers multiple permissions to manage redirects, clipboard, downloads, history, and notifications. Source code is available and support is active via GitHub, Reddit, Discord, and more.
