Double Avatars?
 

You go into Paint. You paste the 2 icons you want. You put one above the other. You save it. You upload it on here.

That's the cheap way.

You actually have to have the avatars just look separate (or not ... your decision) but still have them only be one picture, if I am correct.

Koihime has 2 avatars, but I made them for her. and that is how I did it ...

For me, I make the two avatars, and then I paste them onto a 108x220 canvas with a transparent background and then save it as a png.

Or you can make a gif file. It's an image file that changes at specific timings.
A good example of this is a video picture that is not a video file which is comprised
of several pictures of a subject that changes about half a second each producing
the effect of motion. e.g. : a picture that suddenly winks at you. :wink:

that's a really good one!
