What do you think about a wedding after already being married?

Me and my husband have been married for going on two years this July. We didn't have a wedding, we just went ahead and got married because we didn't want to wait. I always wish we would have had a wedding, because I would love to have pictures, etc. Would it be senseless to have a wedding in the near future? Or is there a certain amount of time we should just wait and then do something like have a ceremony to renew our vowels or something??
