Apologize that this section of NoPayPOKER has been down and hasn't fixed as of yet. This section of NPP is a lower priority compared to other sections of NPP. For example the game servers,lobby,support, etc trump over myspace pics. The techs are working on all aspects of NPP along with their private life of family, jobs etc.. All of the staff on NPP are volunteers, not one of them are paid. (Past rumours spread say different, but they are just that rumours.) For all I know it could be a problem with a bad code in the system. If it is than they would need to take that part down and recode/reprogram it all over again from scratch. (I am not a tech/programmer so I'm guessing on this part) However one day in the future hopefully they will be fixed.
The mod forum is always open to the members to use if they want to show pics of family, or whatever. ONLY members of NPP can see this stuff, it won't be all over the internet to see either.
As for putting up an new, or changing avy's..
Account page,my space , click upload, select a group, click browse to find avy on your pc, click submit, if this is your 2nd avatar then click my desktop, click manage, click main.
Avatar Issues: Title all new uploads in caps. The most recent will be the bottom of your manage list. To organize your existing ones take some time to make each one your main then sit at an empty cash table to see what it is then title it by clicking on edit.
I'm sure if there is any extra information that is needed in this answer, either a tech, support or owner will add to it.
