thumbnails.php problems

[kali]

I've recieved an email from my webhost saying that the above file is draining system resources, and if I don't sort it they'll cancel my hosting and I'll lose my site.

I was wondering if users/admins had any tips for reducing system drain like this.

If you have on the fly watermarking or EXIF reading then disable them. Post a link to your gallery.
