Photomerge equivalent for Gimp?
Solution 1:
As far as I know Gimp itself does not have a way to merge/stitch together photos. There are however various plugins which do this. E.g.
Stitch Panorama http://stitchpanorama.sourceforge.net/
Pandora http://www.shallowsky.com/software/pandora/
There's also Hugin: http://hugin.sourceforge.net/
Hugin is a separate program (not a Gimp plugin), but produces excellent results.
