Go to the tickerfactory.com (you can probably get there by clicking my ticker), register and you can make a ticker. It then gives you the code to input in your signature (in User CP top left) on this site.
You reminded me that I haven't made tickers for my other trips...but coming back to this post I've now realised I chose the same ticker background as you - sorry! It's the only Halloween one isn't it. If I can find another one I'll change it.
Edited to say....never mind it doesn't appear to be showing up anyway so just ignore me! I must have too much in my sig even though it's showing in Preview.
