i agree, but this is in the case you're doing many editings on the pic,
but if the pic is going to it's final edit, jpg is better for it's
compression. i tend to send a lot of photos over the net, and with
upload speeds blazing fast (60 bps :P), it is a hell to try sending
20~30 PNG images. but when editing, PNG is the format of choice
