Hi, I don't know how to get an image off the web and get rid of the background. Can you tell me how?

If the image has a background which has all the same colour, then you can use the bucket tool in the scratch bitmap editor to fill in the background with a blank space. If the image has a background which isn't just one colour, then if you can use an image editing software to get rip of the background, then export it to scratch.

Thanks!
