Re: How to remove all images from product description?
Jason, I really can't tell by your screen shot, but it looks like you're trying to get rid of the Category Icon Image. If you think that you might someday want to display this again, you could just go to Admin>Configuration>Images: Category Icon Image Height/Width, and set them both to 1. That will leave a 1px X 1px image there, but will never be seen. Otherwise, I think it's gonna take a bunch of Category editing.
Or, just don't add images when creating Categories and Products. Of course, I guess that's a little late, now, huh?
