that happend to me too i just turned off my droid and turned it back on and it was there..
I find this annoying as well, there seems to be a delay from the time you take a pic, to the time the new gallery recognizes it. The old gallery never had an issue with this. I still have the multi touch gallery (with no adds), so i've been using that..............even thought he z00m is exponentially better on the native 2.1 gallery app
Anybody else have an issue opening pictures via E strongs file explorer with the default 2.1 gallery............they don't open for me.
