First write your ad the way you want it to read, Devynn. Then go back when you're ready to add links. Highlight "click here for more pics," then click the link icon, and when you get a dialog box open, fill in the box with the correct link for your pics. Voila, you're good to go!
BTW, Devynn I work on the barter system Let me know anytime you need technical help. My normal hours are 9:00 p.m. - midnight! I don't charge extra for mileage.
