I've thought about doing that (before sending my patch) by making a rna_Image_size_get function which return an array like Image.Image.GetSize() did in 2.4x but so far I didn't find how to return an array without DNA stuff. I have already read about RNA on http://wiki.blender.org/index.php/Dev:Doc/Blender_Source/RNA and search some snippets inside svn code and so far, no luck.
Actually I did 2 functions for size_x and size_y similar to rna_Image_depth_get but I think it may be better to have the 2.4x behaviour with a returned array (along with a dictionnary).
