"Some months ago we showed that software patents were responsible for the permanent removal of a GIMP plugin. We’ve finally found the source and binary of this plugins, but it seems as though the author had removed the plugin for GIMP v2.x. It says that “For the GIMP V 2.0, the following additional plug-ins are available in source/executable for download…” For GIMP v2.2, the plugin is on this page. This plugin is trivial and this is the type of thing it achieves. It takes multiple pictures and assembles them into a mosaic. The source code is in pmosaic.c."
