LR HTML Web Gallery -- modified version with great features is available

Question

For anyone using the default Lightroom HTML Web Gallery, one of our associates here has offered a modified version with some great added features.
John Beardsworth's site -- Lightroom Solutions - http://lightroomsolutions.com/ -- is a wonderful resource for LR tips, plug-ins, information, etc. 
The default HTML gallery is fine, but I always found it lacked features.  I mentioned this to Ian Lyons (http://www.computer-darkroom.com/) a couple of years ago, and he sent me a modified version with the ability to specify up to 100 rows by using sliders instead of the grid.  When I tried John's modified version, it had some other good features.  I thought.... what if the two modified versions could be combined?  So, I shot John an email, and low and behold, he uploaded a new version of the gallery to his site.  Thank you, Ian and John!
Here is the link:

Here are the added features that I find most useful:
Number of rows (up to 100) and columns can be specified using sliders rather than the grid
Thumbnail images can be sized to your specification
Filename can be placed on each thumbnail, and you specify size of text
Clicking the large image advances to the next image rather than returning to the top of the thumbnail page (no need to use the 'next' link)
See the site for other added features.  (If you already have John's version, the newer version has the same file name and went online April 17, 2013.)
PLEASE NOTE:  John Beardsworth's HTML gallery is NOT supported by John or Adobe, and is offered "as-is."
I hope others will find this as useful and I have.
John

Answer 1

I've done a version of this where the large file links to the medium and it works no problem. code is based on tutorial code I've already written..
I'd need to see more code to see where the issue might be..
Here's what I have:
(I opted not to put the files in "content", also ignore margin-top, it's not relevent to this)
AddGridPages {
template='grid.html',
rows=model.nonCSS.numRows,
columns=model.nonCSS.numCols,
AddCustomCSS {
filename='resources/css/custom.css',
AddResources {
source='resources',
destination='resources',
AddPhotoPages {
template='detail.html',
variant='_large',
destination="",
AddPhotoPages {
    template='medium.html',
    variant='_medium',
    destination="",
In medium.html
<div id="detailContainer">
<div style="margin-top:<%= margintop %>px;">
<img src="bin/images/med/<%= image.exportFilename %>.jpg" alt="$image.metadata.description"/></div>
</div>
in detail.html
<div id="detailContainer">
<div style="margin-top:<%= margintop %>px;">
<a href="<%= image.exportFilename %>_medium.html"><img src="bin/images/photo/<%= image.exportFilename %>.jpg" alt="$image.metadata.description"/></a></div>
</div>
