I wrote this after being unable to find a similar solution on the web. It is a very rudimentary photo slideshow that is easily implemented inside existing web pages. It requires no configuration beyond supplying it a directory of images and a one-line text file specifying the title of the slideshow. All instructions are included in the source.
The only addition that I foresee adding would be the ability to provide a comment/description for individual pictures. Because I don't want this feature, it's future inclusion depends on requests by others.
