It is recommended that you do not do this as it will no longer split as the ThemeDesigner images will. This means, that all users on your wiki will not see the same pieces of the background. Also, users with slower internet speeds will struggle to load images if they are larger than the allowance. For instance, a 1mb background image would take a dial-up user 2.5 minutes to download it... longer if there are other images on the page. (It would still be over 2 minutes for low end DSL - only 35 seconds for 300kb)
