OpenPictureSpace2 displays a directory full of
pictures in a thumbnail list view. It can display
JPEG, GIF, PNG, and IFF ILBM pictures (including
HAM and EHB specific Amiga modes), and all formats
supported by the SDL_image library. Instead of
showing thumbnails in a grid with a fixed number
of rows and columns, OpenPictureSpace2 packs as
many thumbnails as possible into a every row. The
entire screen space is always used for displaying
the picture.
