cant you just take a picture of which you are flashing anyway? then u dont need to edit anything
.gif files, maybe.
When a man lies he murders some part of the world
These are the pale deaths which men miscall their lives
All this I cannot bear to witness any longer
Cannot the kingdom of salvation take me home?
You need a GIF, so go on Photobucket or Lunapic maybe, and make different colored pictures of yourself, and combine em. Lunapic lets you do animated pictures. Then save it as a GIF, and upload it.
