Yet another xml image thread

Hi.
I use the kirupa xml image gallery,that one with the scrolling thumbnail.
Now I would like to have a short description(from the node named caption) under each thumb when onRollOver.I guess I should use a dynamic textfield?But do I have to create a d.textfield for each thumb,or can I get the x.position of the thumb to be the same as the x.position of the d.textfield some how?
Hope U understand my question.
Would be greatful for anny anwears.
