pho – lightweight image viewer

pho (pronounced like the first syllable in “photo”) is a lightweight program for viewing large numbers of images quickly, rotating or deleting some, and making notes about what to do with each image — for instance, for going through hundreds of images after uploading them from a digital camera.

This is free and open source software.

Features include:

  • Reads any format supported by gdk-pixbuf.
  • Delete images on disk, but it can’t save rotated images. It merely prints out the list of images that need to be rotated.
  • Keywords mode – annotate a directory of images with strings. You can type in phrases for each note, and you can have up to 31 notes. If you use Pho to categorize your photos, you’ll find Keywords mode very handy. You can also type in a unique image comment for each image. Comments aren’t tied to the numbered image flags — each image has its own comment.
  • Slideshow mode, where you specify the interval in seconds (e.g. pho -p -s5 for a 5-second delay between images). You can use this for a screensaver, or just to go through slides automatically. Hitting the spacebar cancels slideshow mode.
  • Presentation mode – full screen, centered.
  • Projector mode – similar to presentation mode but in upper left corner.
