Step 1 : Download WoW Model Viewer at WoW Model Viewer
Step 2 : Save it to your Desktop and run it.
Step 3 : Ok open up whatever "Thing" you want from the Selections on the right. (Click view "Background Color" to change it")
Step 4 : Click f12 when you wana take the Picture and save it in a file in picture's called "WoW Model Viewer" or "Avatar's And Signature's" idc.
Step 5 : Go to Image hosting, free photo sharing & video sharing at Photobucket and signup.
Step 6 : Upload the picture name it etc and then go to "EDIT"
Step 7 : There you can add Stickers,Text,Resize,etc.
Step 8 : Save a copy or replace orignal and then save it.
Step 9 : Then get the [IMG] Code from the picture in your "Albums"
Step 10 : Paste it in the signature box on www.mmowned.com and save it and there's your signature!
