Alt text in Yahoo Site Builder

I am using Yahoo Site Builder to create my webpage, and I want to add alt text to my product images that were created by inserting product modules.
Unfortunately the Yahoo Site Builder editor does not treat them like a normal picture and will not let me add alt text.
What I would like to do is use notepad to modify the html and add the alt text manually...
I thought I had it lastnight, but I obviously did something wrong and the page exploded...
can anyone view source (www . ghilliesuitsource . com) and paste a snipet of of the html code in a reply and demonstrate what code I should place where to generate the alt text, and now cause problems?

Thanks a ton
