Banding or gradient not working

adrianeraldo

Hello. I had this problem and after looking at the forum's posts I found that if I add grain to an image should improve or fix the grading in GS.
The thing is that it also triples the size of my image!
Is that supposed to be that way? or am I doing something wrong?
I'm using a 960 x 640 png24 with no alpha on PS CS5.

thanks
