I have a mac, so I dont have paint, which would be perfect for this, but I need some place, maybe online that I can use that is similar with just a elipse/circle tool, rectangles, lines, text, etc. Black and white is fine. I have photoshop, but I cant make it work for crap. I found one "paint" copy, but it wouldnt let me download the pic to OSX or even save it online. Any ideas? Trying to make a very simple overview of a fish hatchery for a paper.
