Can you check with that user to see if they have background images set to display?
On my own profile, I turned off the background image and while it does not appear on my web profile, the old image URL still appears if you call users/show/epc.xml. Replacing the background image does not appear to turn on background image display. So there appear to be a few issues: - you can turn on/off the display of a background image through the Web UI but not the API - there's no information in the results of users/show to indicate whether or not the user’s background image is to be displayed - uploading a new background image via the API does not cause the image to be displayed Unsure if these are bugs or missing features. -- -ed costello
