Geeqie is a lightweight image viewer. It was forked from GQview. The development is focused on features for photo collection maintenance: raw format, Exif/IPTC/XMP metadata and integration with programs like UFraw, ImageMagick, Gimp, gPhoto or ExifTo
The current development and project can be found on http://www.geeqie.org/. The sourceforge page will be deleted soon.
Despite the existence of geeqie, I still use the old good gqview with my own patches. The reason for this is that geeqie development is poor: it is not even possible to submit a bug report (you need to be "authorized" to do so), and old bugs still remain. In fact, a long time ago I submitted a very serious bug, and it is still not fixed: if you have a folder with many images and try to open only one, geeqie takes forever to open ("forever" depends on the number of files in the folder). The reason for this is that geeqie makes an ordered list of the files of the folder, without purpose (gqview has the same bug). My patch for this is to generate the file list ONLY if the folder panel is visible. A trivial and logical 1-line patch, yet never implemented. It's a pity that geeqie is not evolving, it is a great program.
