The above article discusses how to use a photobooth at your wedding reception. I love do it yourself articles because they get people to be creative and I always enjoy a challenge. However this article is seriously lacking in direction.
“Set up your own photo booth by stringing a clothesline between nearby trees or poles. Attach curtain clips to the top of a large piece of fabric in a color that complements your wedding color scheme, and string the clip loops onto the clothesline. If there’s a free wall available, you could just nail the cloth onto the wall. ”
Serioulsy there ’s never going to be nearby trees or poles at a reception, unless you planted them there 20 years in advance 
This web site has several other articles on photobooths, but unfortunately their how to expertise is sadly very vague and lacking. http://www.ehow.com/Search.aspx?s=photo+booth&Options=0
