It has to be 256 colors, which is probably your problem. Save as a 256 color bitmap. (RM2k3 will allow importing of .bmp files)

Also, in the importer screen, make sure you click on the Picture folder in the left collumn before you try to import anything.. otherwise, you're trying to import a 360x400 Picture into a 320x240 maximum Backdrop.

Maximum size of Pictures are 640x640.
