Can I change IPhone Camera 3GS pixel settings from 2048x1536 to a smaller 640x480 pixel setting? So that all of my photos will be taken at the new and desired lower pixel ratio?

Hi. My Apple IPhone 3GS Camera takes pictures at 2048x1536 pixels = TOO LARGE..

Every IPhone picture that I transfer to my computer must be resized on my computer.

My desired sizes approx after it is 700x525 or approximate near that.

Most of my EBay or Forums require the smaller pixel or MB sized photos.

Can I change the resolution my IPhone 3GS shoots at?

So that all photos can be shot at 640x480 or approximate near that?

Is resetting the IPhone 3GS camera to a smaller pixel size than 2048x1536?

If not, is there a permantent setting inside my IPhone 3GS that I can set the

export pixel output TO ALL EXPORTS to my computers?

I want to have it set as a command and not have to change pictures individually.

*** Maybe you know of options or possibilities I do not know about?

Please help. Thank you
