I’m attempting to alter Rhamej’s photo gallery to my needs and need a little help. The first thing I wanted to do was make it so that each thumbnail would link to the respective link from the XML file. I was able to do that. Now, I’m stuck.
I need to make it so that the respective caption for each XML entry is shown below the respective thumbnail. I’ve tried everything I can and I’m just out of ideas. Can someone alter my AS to do this and then explain why they made the changes they did? I learn best by example - I don’t just want someone to do this, I want to know what they did as well! 
If you need anything else or if you need more clarification please let me know.
