iPhoto 11 duplicate

[EarthNeutron]

Hey, I kinda have a problem with iPhoto 11.
I transferred all my photos from my PC to a 1TB external HDD, connected it to my new MBP and transferred all my photos (arranged in folders) to Finder.
After importing one folder by another to iPhoto, i noticed that it makes a small copy low resolution of each photo and puts it into the same even as the other pictures.
The only solution to this problem that i've found is to delete the small pictures one by one. Is there another way to disable this function without deleting the photos? thx

I would guess these are the thumbnails it uses to display when you are just browsing. Windows does the same but puts them all in a single file called thumbs or similar.

Under Preferences > Advanced is "copy to library" ticked or not?
