This program displays images using the Linux framebuffer device.
Supported formats: PhotoCD, jpeg, ppm, gif, tiff, xwd, bmp, png.
It tries to use ImageMagick's convert for unknown file formats.

Large images can be scrolled using the cursor keys.  Zoom in/out
works with '+' and '-'.  Use ESC or 'q' to quit.  Space and PgDn
show the next, PgUp shows the previous image. Jumping to a image
works with <number>g.  Return acts like Space but additionally
prints the filename of the currently displayed image to stdout.
