Commander, photos in a LARGE quantity should be posted in Spoilers.
Just simply click on "Sp" below the "B" icon and this should appear on your screen "spoiler" ((inside of brackets)) and the same stuff with "/" that ends the spoiler.
Then you will put the images into the spoiler just like you do normally.
So it would look like this:
<spoiler>[img]blablbablablalba.png[img]</spoiler> (the <> are [], because if I typed it that way, it would automatically create an spoiler)
