REALLY small and quick thread
 

Just a little graphic editing, how do you make a picture so that when you open it up there is no canvas behind it? For example, in photo when you open a file that doesn't have a canvas behind it, the picture appears on a grid rather than the blank white background.

How is one to do that?

Oh, and mods, if I have broken the rules then once someone replies, close the thread to save space. This is only a really tiny thing.

If you're using Photoshop, then just delete the background layer.
