You can easily embed videos from sites like YouTube.com or widgets like this example from Slide.com.

If your photographer has your engagement/wedding photo gallery on their website you can link to it here. 

If you use a photo gallery service like Smugmug, Snapfish, Flickr, you can also set-up a link here. 

Save your guests the hassle of having to remember multiple web addresses!

Or, just upload the photos you want to share and display them right on your wedding website!
