We're in the process of reducing the size of our images site wide. One big part of this is compressing the images in our navigation. A tool we've been using to help us do this is [websiteoptimization.com
...] This tool shows us the total size of all of the images on a page.
However, in the details, it is showing images on pages that aren't anywhere on the page, even when doing a view source. After looking into it, these images are preloaded in our css file. It was my understanding that they would only be loaded on pages that are using their div class.
Am I mistaken, or is the tool wrong? Not sure if linking to my site is allowed just for testing purposes, if necessary.
If more information is required, please let me know. Appreciate any replies.
