You will need to make a black and white mask of your first image and use that to cut out the second. Check out this link: http://www.imagemagick.org/Usage/masking/ and have a go.

  • hey sorry I am totally noob about image processing stuff. This is what I've done so far: `convert image1.png -alpha extract _image1.png` then `convert _image1.png -size 300x500 tile:image2.png -compose Multiply -composite result.png`. But the background of the result is black, how to change it to transparent? @Bonzo – Anon Jun 04 '16 at 18:07
