How can I make an icon?Cause I want to put all my inayopendelewa starwars characters together!!!

That is entirely dependent upon what kinds of image edited programs wewe have access to. I make mine with both Paint and Microsoft Picture Manager, which are built into my computer.
Alternatively, wewe could use free online image editors like lunapic.com au photobucket.com.

Photoshop, Gimp, Photopad. Basically any picha editing software out there.
