G'day,
The way this plugins grabbing the JS files and using str_replace() is inefficient. It means WordPress is loaded once for each request. This makes the web server do *a lot* more work than is necessary.
Instead, it would be much more efficient to include the files as static JS/CSS files (no PHP parsing). Then, insert a <style> and <script> tag into the WordPress header on every page.
Insert this at wp_head:
<script type="text/javascript">
var tb_pathToImage = "<URL>loadingAnimation.gif";
</script>
<style type="text/css">
.TB_overlayMacFFBGHack {background: url(<URL>macFFBgHack.png) repeat;}
</style>Then take out those lines from the two static files.
On busy sites, this approach will significantly improve performance.
Cheers - Callum.
