Another change that we've implemented has to do with loading images on some of the "image heavy" pages at AfterDawn. A good example of this is the Desktop pics forum thread. Slow loading pictures in posts or signatures can cause some forum pages to load very sluggishly. Now, after the recent change, all the images in the all posts are loaded "lazily", i.e. when they are scrolled to view. You'll see placeholder images such as this when you view posts. Those placeholders will be replaced by the actual images once your browser has loaded them.
If you encounter any problems with either advertisements or the lazily loaded pictures, please do let us know. When reporting any problems, please make sure to mention your browser and its version, the operating system you're using, and your ISP.
Looking forward to hearing your comments on the changes!
