ok, first of all, if you dont know what youre talking about, please stop answering questions... no offense but youre going to make things worse, resetting the phone wont solve anything, mass storage mode does not work on this phone, if someone can find a way to enable it thats great but as of yet no one has a way on stock or cm, only shinrus aokp has it, but it would mount the sd card not the internal if im not mistaken. and also, its not just pictures that will fill that space, anything you download or create on your phone that goes to internal risks overwriting it, there isnt different memory for videos and apps and all that stuff, it all goes to the same place so anything you have done on the phone since then may have already taken over that spot, but at the same time unless you can find a way to mount usb mass storage mode on your own you may very well still be screwed, or find a program for the phone that can recover things like that, but at the same time, that will install stuff to the internal memory, which will overwrite the pictures little by little and maybe completely. i guess what im saying here is you probably wont ever see those pictures again, and from now on you should just try to be more careful if you really dont want to lose them, there are possibilities but they are all slim ones
