ImageViewer

"ImageViewer" is an ultra-minimalistic image viewing program for Windows originally built with C and SDL2 by Introscopia in 2020.

The 2025-03-23 update brings this little program to SDL3 and to 64 bits! It supports webp again, animations, and now sports multi-image capabilities: Just drag-and-drop image files onto the window!

The Latest update () brings SVG support with plutosvg: https://github.com/sammycage/plutosvg/tree/master which is under the MIT license.

Uses OK_LIB: https://github.com/brackeen/ok-lib which is under the MIT license.
