There's an example in the tmhOAuth github project that has code for this: http://github.com/themattharris/tmhOAuth/blob/master/examples/images.php
The big difference for background images is remembering to send the filename as well. There have also been some users who have found that their version of curl required changing 'image' => to '@image' If neither of those work can you share the image that isn't working and we'll see what could be the problem.
