## Author Notes:
##  My first mod, made by request of one of hte moderators on my forum, to remove
##   images from the signatures in the Trade Forum so that users could not create flashy
##   signatures to draw people to thier trade topics.
##
##  Selecting the forum:
##    At the line 'if($forum_id == 1)' replace the 1 with the forum id (viewforum.php?f=[ID])
##    of the forum you wish to affect.
##
##  Selecting multiple forums (less than half of total):
##    If you have more than one forum you wish to remove images from, change the 'if($forum_id == 1)'
##    to 'if($forum_id == 1 || $forum_id == 2)' for $forum_id's 1 and 2,
##    'if($forum_id == 1 || $forum_id == 2 || $forum_id == 3)' for $forum_id's 1, 2, and 3, etc.
##
##  Selecting multiple forums (more than half of total):
##    If you want to remove image from more than half of your forums, do the above for the forums
##    that _will_ have images, but instead of '==' use '!=', because this way you have less to
##    actually type.
##
##  Removing avatars:
##    At the line '//$poster_avatar = '';' remove the comment slashes (//) in order to remove
##    avatars.
##
##  Replacing avatars:
##    Uncomment the '//$poster_avatar = '';' line, and place something between the quotes in order to
##    replace the avatar with something of your own. example:
##      $poster_avatar = '[No avatars allowed in this forum]';
##
##  Replacing images:
##    Rather than removing the images entirely, you can replace then with something else by
##    changing the line '$replace = '';' with what you want to replace. I you want to use HTML,
##    HTML will have to be enabled on your board and the user will need HTML to be enabled.
##    If you want to use BBCode, you'll have to add the id to the tag. example:
##      $replace = '[img:'.$user_sig_bbcode_uid.']noimgsallowed.gif[/img:'.$user_sig_bbcode_uid.']';
##
##  Replacing images with the image url:
##    If you uncomment the line '//$replace = '\\1';', then only the [img] and [/img] will be removed,
##    not the url of the image. So, '[img]http://mysite.com/myimage.gif[/img]' will become
##    'http://mysite.com/myimage.gif'
