`zgv' is an svgalib-based viewer which views GIF, JPEG, PNG, PBM/PGM/PPM, BMP, TGA, PCX, mrf, XBM, and XPM files, with a full-screen file selector front-end. (It can also view TIFF files if
netpbm's `tifftopnm' is installed.) It can be used as a simple command, with `zgv filename(s)', which bypasses the front-end.
Our Review: zgv is an image viewer, supporting all major image formats. The interface is simple and graphical, making zgv very easy to use. However some users will be disappointed by the lack of ability to use a mouse to select images. Requires svgalib to be installed.
