Just got around to trying the built in photo viewer in Droid accessed through gallery, and what a disappointment! It is frankly a joke. Just tried free app 'picture viewer' and it's better, but still not great. Going to keep looking. What I am looking for is to flick through photos, which picture viewer does, but also being able to pan around pic if zoomed in. Also automatic search of SD card for folders with pictures. PV makes you type in path. Come on!
