Are your SSL pages plagued by the IE warning "This page contains both secure and nonsecure items. Do you want to display the nonsecure items?"
Rather than changing all the links to https://, change them to just //
<img src="//www.domain.com/image.gif" alt="" />
Alternatively, if the images or scripts are located on the same domain, you can access them relatively, rather than absolutely:
<img src="image.gif" alt="" />
Using this method, the browser will know that it must load the image securely if the web page is being loaded securely but it will also load the image normally if the page is not being accessed securely. The image will still need to be available on the other server securely.
