We can probably remove it. I'm curious what about it is really so slow, though. Opacity is used all over the place, and SVGs have been increasingly more popular. Would making the image larger have any effect? I'm wondering if repeating the image is causing issues because it is so small. -- PHP Webmaster List Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
