This is rather complex so I hope I can explain it well.
In CS3 I created my own gallery styles based on the supplied ones. Pretty much cusomizations of the white on black.
When I got CS4, it had a new method of gallery creation, and I wanted to continue to use the types I had already created. I had talked to tech help and was told how to import the styles I had and use the old method.
I am currently creating galleries containing various families of insects. I had previously created a template for bullerflies and moths called Lepidoptera gallery, after the Order to which they belong.. It contains a link to another page which has the families, and the link is called moth families.
Now I was working on an entirely different Order, Orthoptera which includes, grasshoppers, crickets etc. At first I used the Lepidoptera template, but then I had to go into 5 pages that were created and change text and links.
So I created a copy of the Lepidoptera folder, and modified what I needed to change in an HTML editor, which was how I customized the style originally. When I first tried to use the new Orthoptera template, it wasn't listed in the choices. I searched the C: drive and found that the one I modified was in a different directory.
It was in C:\Program Files (x86)\Adobe\Adobe Photoshop CS4\Presets\Web Photo Gallery
So I copied it to C:\Program Files\Adobe\Adobe Photoshop CS4 (64 Bit)\Presets\Web Photo Gallery.
And now it appeared in the list of templates (Orthoptera). So I ran the gallery creator, but found that the page created still had "Moth familes", instead of "Orthoptera Families".
I had modified it already, and did so in both locations just in case. If I go to windows explorer, and burrow down to the file, click on the template itself, orthoptera/indexpage.htm then this will produce a page with "orhoptera familes"
I am just about tearing my hair out with frustration as this makes no sense to me at all. I wonder if anyone understands what is going on. As I continue to make more family galleries, which may have several pages, I don't want to have to keep going into each and doing the same changes all the time. It should be so unnecessary.
