while the developing procede the discrete images solution is the best approach but once sizes of the single parts are decided a single image is sure more easy manageble for whoever would try to modify the graphic whitout have to worry about filenames and coords; but that mean having to write a routine that for splitting the image. I have wrote a rudimental tool for this kind of thing for other projects Im working on so maybe everything could evolve in an import program.

Since we keeping everything always so 'low level' (not a lot of dependencies) do you think the thing will run in maemo5/N900?
Happy sunday
