For the geek that has to do presentations, iSpring Free is a neat little tool that converts your PowerPoint presentations into Adobe Flash slideshows. So no more sticking this slides up on the Web, and needing your visitors to download then open up on their computer (and they need to have Powerpoint Viewer at a minimum too).
iSpring runs on Windows supports PowerPoint 2000/XP/2003/2007.
Well, ispring is good.
I use Wondershare PPT2Flash Standard. It is also perfect. It also can convert PowerPoint to Flash, it is ideal for web sharing, business presentation and creating Flash banner. The special player templates makes my presentation diversification. When I want to make business presentations, I often choose the thumbnail player template to enhance my presentation. It is a good way to Wow up vistors to your website.
To delight, I made a lot of Flash banners for my website with this tool, my friends like them very much.
Wondershare also supplys such samples, like this sample with thumbnail:
