Animated images drug in from finder?

I drug in some images from finder to animate, I removed the animation but the project file size still shows an amount that looks like they are in there. Is there a way I dont know about to removed images from the library?

'Drug' is something entirely different.
Check your 'images' tab in GS - you'll see all images you've dragged into your project from there.
