Problems Using Absolute Paths with SSL

If you are borrowing use of an SSL certificate, such as the one provided free of charge to Internet Connection customers, when a webpage changes from http protocol to https (SSL), if you embed any images by absolute paths without domain names (/images/o.jpg), they will be broken.
If you embed images with full URL absolute paths (http://yourdomain.com/images/o.jpg), the images will show up, but the user will get warning messages that the page is a mix between secure and non-secure items.

On web pages that make transitions between http and https, one should use relative paths to avoid these problems.
