Why the size restriction? I'm working on a sig for someone, and the detail goes for crap and completely destroys it if I drop it below 65kb as a .png.QCDN supports signatues up to 550w x 250h pixels and 65000 bytes.
The image is hosted on a personal site, hence they are getting charged for it and not QCDN. Does the restriction still apply?
I seem to recall asking this before, but can't find the thread.
