not sure if this willh help at all but i had this problem before where my images where gettig very pixelated. the thing i did to solve it was to upload the main image and thumb seperately by editing the post. it solved the pixelation problem. i did have an image that recently got distorted, half of the image shifted over and didn't line up with the other half but when i checked it some time later it was fine. on a couple images that i've seen with this problem after waiting a while and checking later i noticed that it was corrected! sorry if this is irrelevant to the topic but i figured it couldn't hurt to mention it!!! eb
