k, sorry bout that im just used to people being highly confused and dead set on believing they arent. but you are right it does all seem to be there, problem with that is, it may all have to go for things to work right... i recommend copying it all to the sdcard, then doing a factory reset, then try copying it back, if that doesnt work just have a cwm backup ready and you can go back to the way things were
there is a good chance that the old remnants of the gallery app are conflicting with the new version or something along those lines. factory reset may very well solve your problem just remember everything stored on the phone will be deleted so copy the dcim folder to the sd somewhere, make a backup in cwm, do a factory reset, put the stuff back, see if it helps
