yea, i've encountered this problem trying to use a yoda picture....i wanted to select his lightsaber, but i had problems selecting the glow around it. and if you dont select the green glow, all lightsabers look the same b/c then all you have is this long white bar.....and when i selected the green glow around it, i got the background of the picture with it.....help? btw, is this the right forum lol?
if ur talking about a image thats been rendered,just right click and save it and then open and it'll be transparent so no cuttin for u!
Do what I do and don't select it at all, cut it off and replace it with your own: http://www.mickm.com/master.php?page=sabre-tut It's easy.
