adding caption/text to picture on click

wxdqz · Aug 22, 2008

I'm trying to create a gallery where a text link leads to a photo and description on the same page. I confess I have a very feeble grasp on writing scripts.
I have managed to get the text link to change the picture, but everything I've tried so far to get text to change at the same time I've missed something. I have found scripts that will do all this from drop down boxes and thumbnails, but I haven't been able to mesh these. Anyway, the following is the basic text link to image. You'll see that the image part works fine.

Thanks
