Nope, I'm afraid I'm one of the old crocks who can't get the hang of this stuff. I took a picture with a camera (lots, I want to make a gif) then I cropped it (not easy making exactly the same crop on lots of pictures, I bet there's an easy way to do this but I don't know it - anyway it's done). But my new cropped picture has two bright white lumps on the sides showing the bit I thought I had cropped away. So I copied and pasted the image to make a new image, and it still has those pesky white blobs on the side. Is it not possible to make the stupid machine forget the size of the photo it started with? tia
