Copying and pasting from the Internet

[alano9999]

I have a background layer and I want to paste a transparent image to it. I.E I do a Google image search for ‘trees transparent’ and receive a full page of results. However when I select a result with a checkered background vs an image with a white background. Only the ones with the white background copy and paste correctly. The ones with the initial visible checkered background do not. (Pasted image also includes the background with these). I was wondering why..
