I provide high-quality transparent, clean images of in-game Blockland avatars. If you want one, join my server ("Port's Server") and wait for me to be ready to take an image of you which I will then later edit. This is provided entirely free of charge to anyone.
An example:

How to make one yourself:
Good idea, since the process is actually very simple.
- Inspect the object to be pictured, find a color that does not occur in it. Opposites work best.
- Create a glowing wall of empty prints behind the object that should be pictured.
- Take a picture, making sure that the object does not extend beyond the wall in perspective.
- Open the screenshot in Paint.NET or some other image editing program (nope, not Paint).
- Select the background wall with Magic Wand (or whatever that tool is named in the program).
- Press delete, optionally crop some of the empty area away, and done.
