How do you import and image that isn't square

Hi everyone,
I'm trying to make a joystick for my game so I made two circles( one big and one small) in photoshop and saved them as png's. The problem is that when I import them into my game they come up as the whole screen of what I made. Like a big white box with a circle in the middle. How do I get it into my game as a circle and not a square?
Thanks

Here is what you need to do.
Remove the background from your image, so it's just the button. Then save it as a PNG.
That should work
