Files Going to Content—>Files will show you a list of all of the images and files in use (or not) on your website. If you click on the Name, you can see the the item being referred to. The Used in link will let you know where the item is currently in use on published items on your website. Note that it will not only detect embedded images in the Body field, but also attached Front Page Images. A note about PDFs: many times, the Files list will show a “0” even when a PDF is in use. This is likely due to PDFs not being embedded, but rather attached or linked to. Do not assume a PDF is NOT in use simply because it says “0” here.
