Resizing
I finally figured out how to resize images in paint. My computer is norwegian, but all buttons and stuff are in the same place.
Step 1: Start by finding a picture you want to use. Then open it in Paint.
Step 2: Click
Image >> Stretch/displace.
Step 3: A new window will appear, where it says 100% in two places is where you have to change the numbers. But remember that both numbers have to be the same! I've choosen to resize my picture 50%.
Step 4: After you've clicked 'ok' your picture should now be resized:)
