Missing photos

I just checked my memory percentage on WordPress media and it was up to 96.4% well into the red! I am always up there recently because I like posting my own art here. It means that something has to happen so I have been deleting a few photos. I’m down to 96%. Please accept my apologies if there isn’t a picture on one of my older posts… I have to reduce them. I’m also possibly going to post smaller images xxx
