Thats the problem. U cant use Photoshop with animation, u have to use Image Ready.
Post them' pictures here, and I can tell you specificly how to make it.

I had to stretch the flame to 500x150 for a sig then put the skull in the bottom left corner

Well.. u cant say I didnt try. I dont know exactly how u want it,
but here it is.. my attempt:

I just put the skull on top of the flame and filled the remaining transparent area with black, and changed the skull opacity to 60%
use it if you want ;) or u want any changes?

1) Open ImageReady. Open both images.
2) Add the skulls layers to the fire image.
3) With the paint bucket, fill the remaing (transparent) space around each skull.
4) Delete frames 13-25 of the fire image.
5) Last, set the blending mode or opacity.

(basically what Ensomulv said)

here's two examples :

Skull burning in fire (difference mode set for the skull)


Skull made of fire (hardlight mode set for the skull)
