Viewerjs
Viewerjs is a JavaScript image viewer library and frontend media display tool. It functions as an image gallery component and web-based manipulator for rendering images within browser interfaces.
The library enables interactive image inspection through zooming, panning, rotating, and flipping operations. It supports both full-screen modal overlays and embedded inline page rendering to accommodate different display requirements.
The project includes systems for gallery navigation, such as automated slideshows and index-based selection. It provides interface controls for keyboard-driven navigation, UI customization, and dynamic synchronization of image sources during runtime.
Features
