Causes problems in 4.1

This seems very buggy, it renames the images to sequential numbers, so now instead of img223.jpg it is just: ‘1’ , with no extension.

The url looks like this: /wp-content/uploads/1
The File name is still : img224.jpg

Definitely test this before doing major renaming. I messed up about 5 images before I double checked. Uninstalled.
