One of the best ways to entertain a room full of party guests, especially for an 80th birthday party, is with a video slideshow that goes back in time. It does take some work to collect photos and put them together, but the results far outweigh the effort.
Gather old and new photographs from family members to use in the slideshow.
Scan photos not already on a digital camera into the computer. If you don't have a scanner at home, most office supply stores and print shops will do this for a small fee.
If you or a friend is tech savvy, you can easily create a video montage with a program such as iDVD or Windows Movie Maker.
No access to these computer programs? No problem; companies like One True Media will make videos for you with your uploaded photos.
