## Description

PhotoShow is a browser tool that lets you browse and download high-definition images by simply hovering over thumbnails. It works on most websites and supports 300+ popular sites (Amazon, Facebook, Google, Instagram, Wiki, YouTube, and more), delivering instant HD previews without leaving the page.

It includes a rich set of hotkeys and customizable settings to fit your browsing style: viewer controls (Esc to close, X to suspend, Space for reading mode, A/F/L/M/P to switch view modes, V to toggle) and image actions (S to save, C to copy, Alt+C copy address, Shift+C copy caption). Customize how thumbnails trigger the viewer, how and where the viewer appears, and how image details are shown. Export/import settings, per-site options, and other enhancements help you stay productive across sites.

PhotoShow is broadly loved for its reliability, convenience, and rich feature set. Users praise the pop-up viewer and quick actions plus rotate/mirror, making it a favorite extension.
