Being that this is a somewhat slow forum where people aren't posting every couple seconds, make your post, and whenever the wait time is over between posts, post again, except say "Reserved for more pictures" or whatever. Do that 2 or 3 times if you have a lot of pictures, it'll take about 10-15 minutes of wait time however.
