For saving ? No, not at this time.

Yes, which is why we did not add a JPEG saver. It would significantly
increase the size of the binary. Saving an image as JPEG is rather
complicated. It involves color space conversion, DCT, quantizing etc.
It might be a good feature for Command though. For Command and
Command/View the size of the binary is not as important as for View,
because it is not distributed as widely. Same reason why Command has
SSL and other binaries don't.
There are some ways to reduce the size of saved PNGs even from within
REBOL. You could, e.g., quantize the image to less than 24 bits per
pixel before saving.
