Well I didn't have much space to do it and my graphic programs are really limited on text sizes..
anyways i guess at the end of the file list could be a box saying "Advanced" where you can have a list of what main file types to allow through..
Of course it'll only list the universal ones used in ALL computers such as JPG, EXE, GEM, GIF, for WLpM the PLSC. it could go down in a list with 2 check boxes at the side for allow and block. I'll have to start making pictures eventually for that too
