I had the automatically scale images opition on 
(I think it is set to "on" by default) in the 
gallery settings. So the problem is solved =) I 
already resize all of my cel images, so with 
that opition on it just made the quality look 
bad. I just turned it off and all my images went 
back to normal. I was just wondering why all my 
images were fine one day, and then looked like 
crap the next. But thanks for pointing that out 
myers!
