Here is one I made with Paint Shop Pro - it is also in Cat General. Maybe you can use it awhile until you start making your own or have some other folks make you one. There are some TERRIFIC siggy artists here

Oh and to use it, you load it to your image file and then copy the image code like you did your pictures and enter it under User CP and edit profile. It looks like you know where that is because you already have a quote
