Preload and Swap Images- my code is not working

Hey, I'm a javascript newbie and am frankensteining various bits of code I have managed to find on Lightboxes, preloading, and swapping image

Basically, what I want to happen is to run the mouse over the thumbnails on the left side of the page and a larger version of that is in the middle, while information on the right changes to match the picture in the middle. The information is working and the thumbnails appear to be working- at least they go white when running the mouse over them. The problem is the center images aren't appearing at all.

I think the following is the relevant information.

function MM_preloadImages() { //v3.0
var d=document; if(d.images){ if(!d.MM_p) d.MM_p=new Array();
var i,j=d.MM_p.length,a=MM_preloadImages.arguments; for(i=0; i<a.length; i++)
if (a[i].indexOf("#")!=0){ d.MM_p[j]=new Image; d.MM_p[j++].src=a[i];}}
}
function MM_findObj(n, d) { //v4.01
var p,i,x; if(!d) d=document; if((p=n.indexOf("?"))>0&&parent.frames.length) {
d=parent.frames[n.substring(p+1)].document; n=n.substring(0,p);}
if(!(x=d[n])&&d.all) x=d.all[n]; for (i=0;!x&&i<d.forms.length;i++) x=d.forms[i][n];
for(i=0;!x&&d.layers&&i<d.layers.length;i++) x=MM_findObj(n,d.layers[i].document);
if(!x && d.getElementById) x=d.getElementById(n); return x;
}
function MM_swapImage() { //v3.0
var i,j=0,x,a=MM_swapImage.arguments; document.MM_sr=new Array; for(i=0;i<(a.length-2);i+=3)
if ((x=MM_findObj(a[i]))!=null){document.MM_sr[j++]=x; if(!x.oSrc) x.oSrc=x.src; x.src=a[i+2];}
}
function MM_setTextOfLayer(objId,x,newText) { //v9.0
with (document) if (getElementById && ((obj=getElementById(objId))!=null))
with (obj) innerHTML = unescape(newText);
}

<img src="imagetmb.jpg" name="boxd" id="boxd" onmouseover="MM_swapImage('boxd','','whitebox.jpg','','image.jpg',1);MM_setTextOfLayer('info','','Info<br /><br />Ink on Bristol Paper<br/><br />13 x 17 in<br /><br>May 2011<br/>')" onmouseout="MM_swapImage('boxB','','imagetmb.jpg',1)"/>


I think it's because the images in the center don't have a source, only a name, but I'm not sure where I would fit that in. I tried putting it in the second set of code, but it did not work out.

Oh, my...more DreamWeaver code. Or, as I much prefer to call it, DrunkWalker. Or NightmareStalker.

KILL THAT CODE!

If possible *NEVER* use any JavaScript created by DuckWhacker.

There are *MUCH* better solutions out there. (Well, almost any solution is better.)

Look for "javascript lightbox" via Google and prepare to be inundated with GOOD solutions.

If you really don't like any of them, then post your HTML here (without the DoofusWonker code), and we can help you create a custom solution.
