I wouldn't have a problem with people posting pictures of themselves at my wedding, but I'd personally much rather the pictures that get posted first be the good pictures by the photographer, and not the red-eye, strange-angle, mouth-open, squinty-eyed pictures that a lot of people I know take. Otherwise people will probably see the first pictures taken, glance through, satisfy any interest in seeing wedding pictures, and never see the good ones that get posted later. So I'd much prefer that for the posed shots (and maybe for the special shots, like father/daughter and mother/son dance, cake cutting) the bride/groom get to post the shots first. Same with a new baby, I'd rather the father/mother get to post the first shots and the grandparents, siblings, and friends wait to post their shots until later. I also sort of see it a bit as letting the person whose event it is to be the one to make the "announcement" (even if the announcement is pictures and more of a "and this is what it looked like" thing). But, again, no problem with people posting photographs of their group at the table, or them dancing, or whatever. Just think they should wait for actual shots of bride/groom and special parts of the wedding. Wait forever? No. But maybe a few days after the bride/groom get back from the honeymoon, unless you know they don't mind because you've talked to them about it.
