I have noticed that a lot (if not all) the images downloaded from Greenfoot are NOT rectangular in shape.
That the image is the shape of what it portrays. But, if I edit the image, my new image is always rectangular.
I get a box around my image that I do not want. How do I avoid getting that box?
By the way, I am using Paint. Should I be using something else? And if so, what?
