iWeb: how to add a linked image?

I need to add a "book now" button to my web site. How do I do this in iWeb?

1. Drag the "book now" graphic onto the page.

2. With the graphic selected, use the Inspector to assign a URL to it (so that it directs to the booking page).

Thanks, Chas. I actually got it figured out.... they gave me an html code, that I pasted into that little html widget-thingy there, and it works beautifully. But I'll remember your instructions for other needs!
