This slideshow presentation is a Powerpoint display uploaded to the web using Slideshare. It was created fro the recent Tasmanian SA conference. This is a site well worth a visit to browse through the many creative ways, Powerpoint presentations are harnessed for web sharing.If you can create your PP folder/file this can be a better way to present images and the like than through other photographic means. such as Bubbleshare and Flickr, etc. Slideshare also handles and accepts (ppt & pps), PDF, & OpenOffice (odp) files. So if you wanted a cheap/free software to create your presentation for this you can use the Open Office suite.
Another way to do it would be to get yourself a Ubuntu Live CD (and if you didn't want to intstall Ubuntu on your PC you can boot from the CD and use the Open Office software which comes with the Ubuntu CD package
