liqmap is designed to pan/zoom the most recently selected image, there is an early version on one of the maemo repositories. its a widget/app that I use all the time on my playground, but it runs as a standalone app. the one currently on the repositories has a file select dialog that tries to generate its own thumbnails in the image select and is suboptimal unless the cache has been built. i have remade the file select dialog recently and it uses the system thumbnails now and looks a little cleaner and certainly cleaner for first run. the library it sits on (liqbase) is just being optified also and are due v soon.
