[wp-hackers] What do the key's mean on wp_attachment_metadata

[Mark Harwood]

Hi Ryan,

Thank you very much! quick google of "unserialize the value as an array" 
and im all sorted and understanding :)

Im self taught PHP Dev, so i tend to learn most things when i hit that 
development brick wall :D (dont we all?)

Thank you very much!
