Little Help with some jQuery Overlay

Been banging my head on this problem for a little while and it's getting late hopefully someone will see what is wrong with the code.  I am using jQuery to have a vertical scroll box of images which fill a div to the left of it on mouseover.  All of this part of the code works fine.  I am trying to implement a lightbox type effect using the jQuery function overlay.  This seems to work great so long as I do not use javascript to switch which file is loaded.  If I use the javascript I currently have to switch the images, the images themselves do appear however the close button never appears in the upper right corner as it should.  I have tried a few different things to no affect.
The image code which works currently can be found on line 129.  What I want is to comment that out and use the js function "setImage" (currently set to "ssetImage" to allow the working code to run properly on line 147.
Hope someone can tell me what I am doing wrong here...  Thanks in advance!

Here's it working with a single image for the overlay:
