Class GD located in sapphire/filesystem/GD.php

static function color_web2gd($image, $webColor) {
   if(substr($webColor,0,1) == "#") $webColor = substr($webColor,1);
      $r = hexdec(substr($webColor,0,2));
      $g = hexdec(substr($webColor,2,2));
      $b = hexdec(substr($webColor,2,2));
      
      return imagecolorallocate($image, $r, $g, $b);
   }

$g is the same as $b should be $b = hexdec(substr($webColor,4,2));

If image gets corrupted during upload process i.e. network problems, resizing function will throw Fatal Error or cause a segmentation fault.

Cheers Mateusz; again, like Elijah, its great to see you Google Summer of Coders scanning through code and providing patches, which, as Andy suggests, are now available for download This supports how you've been ranked for Google to approve for tomorrow's judgement day
