Have native resize capability in GR?

Hi!

I would be nice to be able to select native Java image resizing (I guess some kind of image processing exists in Java) in GR.

I'm thinking when you are away on vacation or something I want to upload photos from an Internet cafe or a computer where you can't install your own applications like ImageMagic.

I know you can send pictures in original size and let the server do the resizing, but then you need a fast connection and also, alot of servers don't have a PHP memory limit to handle resize of pictures bigger than 6-7 Mpixels.
