So, you wanna make your own, easy avatar out of an already existing picture? If not, then get the fuck out.
Steps:
1. Open up MS Paint.
2. Find the picture that contains an image that you want to be your avatar.
3. Use the rectangle select tool, select the area you want to be your avatar and cut or copy your selection.
4. Click File --> New. Do not save.
5. Paste the image you copied/cut from your previous picture.
6. Resize the image so that it's about the size of a normal avatar.
7. Save it, and you're done!
