#1 have to have pictures on your computer

#2 a program to "play" with, with the pictures. I have Live Pix, Kimlovescats has Paint shop pro, I am sure there are many others out there just as good as those.

#3 create the siggy you want, upload it to a web storage like Imagestation.com, Shutterfly.com, Photobucket.com or others so that you can post it.

edit... If you have pictures uploaded to one of those storage sights and post on your thread... Someone can make you one if you don't have a program... There are several threads asking if anyone wants a siggy but they have to have pictures to do it with. I make them too...
