ajax photo album with text description

I'm trying to create a 开发者_如何学编程little ajax photo album with text description... now I've created this http://www.brucisystems.com/petrilli/testajax.html

Now, what I want to do is to remove the dropdown list, insert the first photo with description when I oped the gallery, and to put a button on the bottom of the gallery, and clicking on this button then the picture and description changes, but the problem is that I have no idea of how to make it: do you have some hints?

Thanks a lot

Best regards

Why don't you just move

<div id="txtHint"><b>la foto apparir&agrave; qua</b></div> 

at the very top? IT will do your needs
