Same here! Working on a client website and decided to try Squarespace versus my Wordpress resource. Uploaded a ton of FPOS and went to clean out the image library and learned that you can't delete imported images. WTF? Who in the world thought this was a good idea? HUGE FAIL! Without that function I will never use SquareSpace for another client website again. This client now has a TON of images that will never be used.
