One of the best reasons in the world for avoiding the entire genre: leave it all to family and friends who will never have to carry the responsibility nor the balme for anything. Who ever looks at old wedding pictures anymore? About the worst thing I see in some otherwise beautiful homes are those silver photo-frames filled with stilted images of black/white fashion modelled by nearest and dearests! Fill'em with happy snaps, by all means, but let them be real pictures, not just another form of passport photograph.
Should anyone think that feeling redolent of cynicism or bitterness, think again: marriage was the single best thing that ever happened to me in my entire life. It's not marriage, it's the bullshit built around the event that sours.
