According to Susan Lister, OpenOffice.org is a good tool to convert your Powerpoint presentations into good looking web pages.
Susan is dissatisfied with “clunky ‘powerpoint to webpage’ slideshows”, produced by MS Powerpoint. so she looked for a better solution and found it in OpenOffice.org Impress. She discovered:
These experiments showed that I can make a better web page set up using Open Office – my final website was a smaller file size as well as smaller in the amount of screen real estate. I liked the fact that html wizard gave me control over whether I wanted frames, show notes included and a title screen as well the size of the final presentation (640×480, 800×600, 1024×768).
Susan discovered, that the HTML web pages created by Impress not only look better but are also smaller by a factor of 10.
