I will add one soon. I just need to find some. Yes I will add more categories soon. I haven't had much time to add any new sections. But I have been looking for new material.
Good images are harder to find than most people think.
I realize that the Birthday Section is lacking. I'm looking though. It's hard to find good birthday photographs. Keep in mind though that a birthday card does not have to be from the Birthday Section. You can use a card from most other sections to wish someone a Happy Birthday.
