How do I delete images from an SFF without using FF? Because I deleted some images that other sprites were linked too, but the linked images are still there and when I go to them and delete them or try to do anything else, FF shuts down.

Nevermind...I just went around the glitch. Instead of deleting it, I just switched it with another image with the change option. Now I need to redownload the sprites and fix all the sprites I deleted...I don't remember what I deleted either.
