Rework image slider

Rework image slider

Hello,
i found a simple slideshow scipt on  this page, wich works nice for me. 
The only problem is, i can´t add descriptions/caption for pictures. This way i need help for a rework.

The creater has written in the comments the easiest way should be to use a div for each image and a span with text in it.

 I tried and changed in the Jquery the img tags with div tags, but i dont get it to run (im a beginner :(). 

I added the Code on  JSFiddle Click. And  here the updated Code i tried, but the images are´nt showed more.
