Save and transfer high resolution image

I want to save a big resolution (1600*1200) image with no compress format. Current it only supports .bmp file. Then I want to tranfor it to a network space with wifi, but the size is too big and the tranfer speed is too slow. So it there any plan to support .png format? Or it there any other way to support this need?

The PNG format is for computer graphics. We have partial support for it already. But, you should not use that to take images… JPEG with a high quality is the right approach.
