All of this is very possible and acceptable. If like me you don't have the Powerpoint technology to share screen etc then you can send the information to your host if they are willing to show your pages/videos/recordings/photos. The problem with this is you are relying on others and they need to know precisely when you want them to share your media, which can cause problems. On the other hand if you aren't a technowhiz yourself and try to share yourself this can cause disruption.

I would recommend you try it with a smaller non-paying group first to get the hang of it. I've got my 4th presentation coming up soon and the soundbites I need playing are all already online so that helps. I just need to point the host to the right place so he can capture them. Photos I'm finding a bit more tricky. The most successful presenters I've seen know what they're doing and have it all set up on some sort of Powerpoint.
