Topic: Supported Image Format: Add More?

How about support for alternate formats to the standard .jpg -- for example .pdf / tiff - for local use this could be great (although it has limited obvious application online). I've got a project in mind for a .pdf version of autoviewer. Would it be possible to tweak the viewer if i went 'pro', so it would recognise alternate formats- or is this beyond us mortals.
