iPhoto Library: transfer FROM external HD TO iMac's HD

[pilotkid]

Hey everyone. Awhile ago I transferred and set it up so that my iPhoto library was on a external hard drive. I would like to undo what I did. I want to move my entire iPhoto library from the external hard drive that its on to my iMacs hard drive and keep it there. I need my external hard drive for something else and don't want to go out and buy one, and I have 600gbs free on my imac and my iphoto library is about 20gb's so I figure i'm good to do this.
So how do I do it?
Thanks ahead of time!

Isn't it just a matter of copying the iPhoto library to your Pictures file in your Home folder? Remove the old one and then when you start up iPhoto, it will ask you to link to iPhote library.
