As others have said, this is not a very compelling reason to reject the 
request. What bothers me more is why it should be a UA's job to 
restrict uploads based on pixel size of images, and not on other 
things.

Should UAs be able to restrict uploads based on the bit depth of 
images? (For some purposes only 1-bit images are desired.) How about 
based on whether images are animated or not? (Some forums may want 
avatars to be non-animated only.) How about based on the number of 
pages in a PDF or RTF document? (Job application forms may want resum?s 
to be no more than /n/ pages.) How about based on the sample rate of 
audio files? Or on the framerate of video files? At what point do you 
say "okay, that's the server's job, not the client's", and why?

(Keep in mind that any restriction done by the client will still have 
to be done by the server as well, to guard against buggy or malicious 
UAs.)
