Yes, it is since long time on my to-do list. But note that your pictures must be resized to proper width/height, black borders cropped and then recompressed to jpeg, so even if such feature existed a manual operation from an admin would still have to be done.
If you provide pictures ready-for-upload they are often processed faster.
