well... for the data storage portion go to setting>connectivity>USB Data Cable> and then Data Storage... or Musci Sync.. on of them will let you use it as a drive and let windows copy the pictures... the other one i'm not sure, but if you go to mem card of the phone, and then pictures or i think the camera setting... it lets you change the way the phone save the picture file names... see if that helps at all??
No, the only thing that I see that's a way to change filenames is I can change the name part, not the numbering system. For example, I can make it say picture001, instead of image001, but it still numbers by filling in the missing numbers that were previously removed from the phone. That's just a dumb way of doing it, I think.
