How to delete original photo's that have been retouched?

Question

For Ex: I'll have 8 similar picture's of my ferret's that I have retouched in order to look better--but how do I delete the original 7 that I don't need anymore? And this goes for practically my entire library--I have about 1000 photos with about 8000 similar duplicates--that I don't need.
How do I get rid of these . . . and I've tried iPhoto Diet--and (I might be using it wrong or something but) it doesn't delete more than 3 or 4 photos after about 30 mins. and like I stated above I need to get rid of about 7000 more photos.
I've tried going thru each and everyone deciding if it was the better "retouched" photo but it takes light years to go thru my entire library.
Any easier way?
Thanks!

Ok, let's try:
In the finder sidebar, you should have the different Music, Applications, Pictures Icons. In Pictures there should be one folder called iPhoto Library.
I set up a Smart Folder (in Finder > File > New Smart Folder), searching for the term 'original' within my Pictures folder.
This folder should show you all the Originals folders within the iPhoto Library.
Clicking on List View (Apple-2), you can sort your Originals folders (well, at least the search results) by Date, if you know you edited some pictures today or yesterday, or by size, finding the most edited pics from one day.
Clicking on each of these Originals folders will reveal the original, unedited pics (which you probably wanna throw in the bin, if you don't need them), as well as the MPG movies which some digital cameras can make. So be careful with throwing away the whole folders before checking the contents.
If I really want to keep an original shot, say if I do some major colour change in Photoshop for example, then I usually duplicate the photo within iPhoto. This way I can edit one, and still keep the second, both visible within iPhoto, without having to worry were the 'invisible' Original is.
I hope this makes things clearer. Let me know, if it helps.
