Create Dynamic Content (Portfolio Plus Built in WordPress Slider)

I was able to change the background for the Single Portfolio Page & Place a built in WordPress Slider on the page.

I have a unique situation where due to the template I am using, the plug in sliders will not work.

So, my boss is asking me to dynamically change the short description (etc) based on the Meta Data of the photo in the wordpress slider (Caption, etc).

How can this be done? (Hacked using PHP?)

Thanks!
