No! In my opinion you should never have to pay a monthly fee or something like this to list your photos. None of the agencies listed on this site work that way. On the other hand, they won't accept everything that you upload either.
Basically, you should pick an agency (I recommend starting with the top 3-4 on the
rankings list for photographers and sign up for an account. They normally want to see a few of your stock photos (or illustrations) before they will accept you as a "photographer" Some are easier than others, but there is no harm in trying it.
Good luck.
