I don't see any error when I load the page. I'm using the Microsoft EDGE browser.
While viewing the page, hit F12. Then look for the Console tab, near the bottom of the developer's toolbar. It shows the error. Here's what I see in Edge, attached.
That message usually means that you need to make the album again, making sure you don't tell it to process only updated subdirectories, and then upload it again. Don't try to "pick and choose" files to upload. Use the jAlbum uploader, which is much faster than something like FileZilla, and doesn't make the mistake of not uploading necessary files.
I tried how the local album behaves in Edge. On the local album stored in my E:\ drive the link to the slide page is working.
I attached two screenshots showing the link in the bottom line of the brwoser window when hovering over one of the thumbnails, one for the local album and one for the uploaded album.
The link in the uploaded album refers to the newimages.html page.
I also added a screenshot of the jalbum preview of the album. Also her the link refers to newimages.html
