Alternative documentation using DataExtension instead of extending the Image class

Hey,

just a suggestion for an alternative doc using DataExtension.

i'd prefer this over extending Image directly as your custom Image Type sometimes conflicts with the Images uploaded via the "Files" manager, resulting in not beeing able to select Images "from files" in the uploadfield anymore.

just my 2 cents, though :)

thanks for the plugin btw. used in an couple of projects already

cheers
