User submitted photo in a lightbox

Question

I am absolutly perplexed. I'm trying to create a user submitted classifieds site, so users can sell items.  I would just like for the user to be able to submit photos and then have them display in a lightbox.
I downloaded a simple lightbox gallery into dreamweaver then uploaded the site to BC.  It came with demo images and worked fine (code below):
<div id="gallery1" class="lbGallery">
  <ul>
    <li> <a href="images/lightboxdemo1.jpg" title=""> <img src="images/lightboxdemo_thumb1.jpg" width="72" height="72" alt="" /> </a> </li>
    <li> <a href="images/lightboxdemo2.jpg" title=""> <img src="images/lightboxdemo_thumb2.jpg" width="72" height="72" alt="" /> </a> </li>
    <li> <a href="images/lightboxdemo3.jpg" title=""> <img src="images/lightboxdemo_thumb3.jpg" width="72" height="72" alt="" /> </a> </li>
    <li> <a href="images/lightboxdemo4.jpg" title=""> <img src="images/lightboxdemo_thumb4.jpg" width="72" height="72" alt="" /> </a> </li>
    <li> <a href="images/lightboxdemo5.jpg" title=""> <img src="images/lightboxdemo_thumb5.jpg" width="72" height="72" alt="" /> </a> </li>
  </ul>
</div>
<script type="text/javascript">
// BeginWebWidget lightbox_gallery
                    $(function() {
        $('#gallery1 a').lightBox();
  // EndWebWidget lightbox_gallery
</script>
The tags for my photos are {tag_main photo}, {tag_photo#2} and so on to photo#5.  I had hoped that I could just delete the current image source and input my tags and the lightbox would function however it does not.  When I examine the code on the displayed page it shows that the tag does something like this...... <img src="src=........in other words the tag element supplies the command "src=" and messes things up.  If I remove the original src= command BC automatically alters the code and everything gets messed up.
Does anyone have any ideas, or even idiot proof code I could use (I'm still figuring this out and probably can't handle intense coding)
Thanks

Answer 1

First, thank you both very much. I realize this question is probably very elemenatry but I'm still getting the feel for these features (such as lightbox) and as you can tell, having some difficulty.  I updated the code as you both suggested and it brought me one step closer, the pictures now display in the web app as desired (here's the page http://yourboatconnection.businesscatalyst.com/boat-classifieds-1/324553425 ).  I'm still having as issue though.  When I click on them instead of opening up into the lightbox, as they do in the Live View in Dreamweaver, they now just open up full size in a new tab.  Maybe I don't fully understand how to implement the code supplied with the widget but I added the below code into the CSS.  Below that is the current, updated web app code.  Maybe there is something obvious that one of you can see.  I just want a simple thing to present the expanded pictures, I really didn't think this was going to be that difficult -silly me! Thanks again.
