I have received a lot of advice, but no concrete help.

Question

For the past two weeks I have received a lot of advice, but no one told me what to do in a concrete way or demonstrates on my example. Is there any one who can do this and help me ??????
I'm trying to write an application which has to show my image files (set of photos) with a text description. The list of image files placed into the JList. So, when I select a file from the JList it shows me an image (everything is OK).
But, every image has it's text description in MyText.text file. It's a file with each text line for every image. Actually, I am trying to connect two actions - showing my image and setting it's specified text line description (from MyText.txt) in a JTextArea. I thought that the best way to do this with my text it is like I did it with my images through Vector. But No Success.
Here is my application. I have indicated with ** in my code how I am trying to do it.

Hi
Look at this program and i am sure it will give you some ideas, (actualy all you have to do is to add the images names in addPicList(), and to add the text in setText(s).
