It's only the right corner, the left one is okay. An easy way you can do is copy the left corner, use mirror, paste it to the right corner if it's a whole image and that should clear the problem. If it's still not smooth use a slight "soften" effect to get a good effect.
hehe, guess i didn't pay close enough attention to that. I actually did the mirroring originally, but that doesn't work quite the way I want it to because of the shadow added to it, I think it looks the way it does as well because I save the image larger than what it is displayed on the site, so when it resizes, it distorts it a little. Will be fix ASAP, thanks again.
