When you drag/drop a image in FGC it's prefaced with "Drawing:" which is odd since it's an Image. It's far more likely that you might have a Drawing on a image in FGU than FGC. Is this configuration backwards?
Code:<string name="library_recordtype_single_image" version=">=4">Image</string>
<string name="library_recordtype_single_image" version="<4">Drawing</string>
