Well you know what I do...I don't have any problems with the dimensions..I'm currently using a custom clan spray created in Fireworks MX 2004....with dimensions 828x1175.....and it works great...no complaining by CSS. The secret is to use it as bmp-file and not jpg or jpeg...this way you can use any size you want and great quality is the result! If you have a jpeg or jpg picture that is bigger than the allowed dimen. then open it with Piant if you don't have Fireworks or something similar. When you open with Paint click on File-->save as then choose 24bit BMP as fileformat and then SAVE. Try it this way...it should work with any size in CSS, at least it works for me and all the other members.
