How do you change the order of picture files on the Samsung u740?

I just got the Samsung SCH-u740 from Verizon and it seems the phone automatically orders the picture files by size. This annoys me to no end b/c photos I take from the same day or event are all over the place when I open ';my pics'; and I have to search through tons of other photos to find them one by one. Does anyone know if you can/how to change the way photo files are ordered - either by file name or date added? Thanks!How do you change the order of picture files on the Samsung u740?
