a bit like your example "Multiple Galleries on Separate HTML Pages"
This example essentially duplicates a template file for each gallery so that each gallery has a separate page containing both the gallery and the menu.
As an alternative, you could create a single page with an <iframe> and load the galleries (from links on your page) into the <iframe>.
First of all, create your galleries, keep them all in their individual folders and upload all the folders (not just the contents) to your web server. In this example, the gallery folders will be named 'gallery1' and 'gallery2'.
On your menu page, you would have an <iframe> such as:
<iframe id="content" name="content" src="gallery1/index.html" width="800" height="600" frameborder="0" scrolling="0"></iframe>
You would also have links such as:
<a href="gallery1/index.html" target="content">Gallery 1<a>
<a href="gallery2/index.html" target="content">Gallery 2<a>
... which would target the <iframe> with the galleries.
Incidentally, the reason your current gallery is not displaying may be due to a typo in the following line:
'vcore' should be 'svcore'.
