I get the following warning:
Warning: Unable to fork [cmd.exe /c c:\netpbm\\jpegtopnm --quiet "c:\program files\apache group\apache\htdocs\albums\album01\aac.jpg" | c:\netpbm\\pnmfile --allimages] in c:\program files\apache group\apache\htdocs\gallery\platform\fs_win32.php on line 148

when I run this statement
return exec("cmd.exe /c $cmd", $results, $status);
