OK, I'm really bad at giving lessons but I'll give it a try. Here's
Google Images. Type in a character and find an image you like. Click on the image;it will go split-screen-half the image you found, half the web-page hosting it. On the top half where the image is click on -see image alone- or -enlarge this image- when it is alone highlight the address and copy it.
Go back to this page,add reply and click "image" just below the typing box. Paste the address in there. Ta-dah! If it's not a protected image it will appear. I've had to delete several because sometimes you don't know if their protected unless you try.
