Bart,
Thanks for your help. My web sites have always been as much about professional development as photography. My main site is Dreamweaver "Spry" based and is around ten years old. It only has approximately less than a dozen html pages. However, the site has multiple pages that are generated using a simple html based database process.
The slide shows are created using jAlbum's "BananAlbum" skin. It seems to have become more mobile friendly in the past decade.
"BananAlbum offers a streamlined experience where the emphasis is on your photography and not on the package.
Create single albums or a full featured portfolio site.
You can choose between various styles and typefaces, customize the colors, define the size and position of the images and thumbnails, and way, way more.
For mobile devices such as the iPhone, iPad or Android, BananAlbum switches to a viewing mode that is optimized for small screens with touchscreen".

Something to think about.
