After you upload image files, they live in your Content Library, where you can easily pull them into documents. We prefer the Content Library system because adding an image by its URL leaves you open to losing your image if the URL changes.
When an image reaches your Content Library, it stays there until you decide to remove it. (Collaborate provides unlimited storage.)
