Here's another one. You're welcome to use it if you like it. If not, no big 
It's two images, one on top of the other (because it's larger than 100 pixels in height) so you would need to add two image tags to your siggy box. The second image tag needs to be one line below the first image tag so that they show up on different lines but without a space between them.
If that doesn't make sense let me know...lol
