Upload your pictures to something like
www.photobucket.com. Then, when you go to the page where you can edit your signature, paste the img code that looks kinda like this:

To get tickers, click on the ticker someone else is using. It'll take you to the ticker-making website so you can create your own. Then you can paste the "bb code" into your siggy just like you did for the images. If you want a fancy signature that isn't just a plain picture, go to the
siggy forum here at JM and request one.
Oh, one more thing. When you want to change the font of something, type the whole thing out first. Then highlight the text and click on the font options you like. If you click the font buttons and then start typing (like you would with a word processor like Microsoft Word), it won't work.
