Hornil Photo Viewer: New Lightweight Image Viewer
Hornil Photo Viewer is pretty much no frills and there are certainly many more better known alternatives available but it fills the need well enough for a basic image viewer. It features a file tree on the left, several ways to list or view images in the main section and a histogram, waveform, exif info (and the option to remove the info) and thumbnail viewer on the right.
Other features included are full screen mode, view in slideshow, image zoom, flip, rotate and convert and a launcher for any external image editor. The familiar keyboard shortcuts are available too, for example Ctrl+PgUp and Ctrl+PgDn to navigate through images. The supported formatted are png, jpg, tif, bmp, ico, jpc, pcx, tga, tif, ico, jpc, jp2, pcx, pgx, pnm, pgm, ppm, ras, ska, wmf and tsp. Hornil Photo Viewer runs on XP and newer.
