“Latex2slides is a simple graphical program that produces a set of HTML/JPEG slides from a TeX or LaTeX source. Each Postscript page is converted to a JPEG image using ImageMagick's convert. The program then makes one HTML page for each JPEG (or slide), and an index.html page. As a result, each page in your slide presentation corresponds to one of the Postscript pages you would obtain from the LaTeX source. ”
