Chuck,
A couple or minor issues:
Line 45:
<br />$stylesheet = "/usr/local/apache/htdocs/ubbthreads/stylesheets/$fstyle.css";<br />
can be changed to
<br />$stylesheet= "{$config['stylepath']}/$fstyle.css";<br />and line 1510
<br /><link rel=\"stylesheet\" href=\"/usr/local/apache/htdocs/ubbthreads/stylesheets/$fstyle.css\" type=\"text/css\" /><br />
can be changed to
<br /><link rel=\"stylesheet\" href=\"{$config['stylepath']}/$fstyle.css\" type=\"text/css\" /><br />Also you can pass a text string in the $html -> send_header("My Site's photo gallery", $Cat, 0, $user); to make it a bit more consistent with your site.
