I’ve just completed the deletion of a large number of image galleries dating up to about 2013. I was using Slideshow Pro to run those galleries. As the product is no longer supported, and was eating up about 8 gigs of web space here, it was time for it to go. I suspect most of the galleries were private anyway, so it may not make much of a difference, but if you see an older blog post with an empty gallery or some kind of error message, that’s why. I still have all those images on file here, they’re just not on the website anymore.
