Adding Thumbnails Question

Hello everyone.

thanks to everyone who contributed in the adding thumbnails tutorial as it is very useful to me. exactly what i wanted.

i have maneged to make a similar kind of setup but i am having trouble with one thing that i wanted to add:

In the description text (textarea) for captions I want to display 10-12 lines of text and also add some hyperlinks and bold headings. This will be different for each thumbnail (project) so it will have to be dynamic again and data used from XML file.

10-12 lines are not a problem but i am having trouble with showing hyperlinks and bold to some headings. Any help will be sooooo great.

thx
