I have just got the photography contract for 25 themed fancy dress parties leading up to Christmas with 450 guests at each. We are taking photos at the event which people can buy on the night. Rather than printing out the photographs before they have been purchased, we are going to use a large tv to display them. I have been looking for slideshow software that would show multiple thumnails in a slideshow rather than one picture at a time. If the software could show say 10 at a time this would be ideal but I cant find anything that does this. Has anyone else done a large event like this before where you sell pics on the night?
