I used to use the Automate -> Photomerge option in Photoshop CS3 to stich photos together. Is there an equivalent function in the latest version of Gimp? If so, how do I access/use it? If there is another solution please let me know, too.
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/
There's also Hugin: http://hugin.sourceforge.net/
Hugin is a separate program (not a Gimp plugin), but produces excellent results.
