[wp-hackers] Hooks on image upload

[Mike Plant]

Hello all,

I have recently joined the list and have been quietly listening. This message is exactly what I joined he list for. Recently while building a plugin I need to crop thumbnails from the top left instead of centering as the core does now. I could not find any way to change this without changing the Wordpress include. 

What are the thoughts on adding a hook to the crop function in media to allow a programmer to change the crop parameters?
