Both approaches seem complicated so maybe a different dump would be helpful:
Page id --> List of [ Image id | real url | type (original | dim_xy | thumb) | license ]
http://commons.wikimedia.org/w/api.php?action=query&prop=imageinfo&i...
Returns image URL, width, height and thumbnail URL for a 200px thumbnail.
