WHen I make a sig and put it on jsp and use it, it looks high quality, after a while the image quality suddenly looks bad and choppy, why? I use photoshop

Just upload it again maybe?

Otherwise, it never happen to me and my sig is like 1-2 years old.

I can reupload it, and it looks good then after a day it looks bad again

either 1 of 2 things:

1: your image hosting sucks and they go in and take your picture and downsize it just to piss you off
2: your eyes are bad and cant tell the difference.

i think im going to go with #2
