When you use the Resources tool to upload an item, you can choose to keep that item accessible only to members of your site, or you can choose to make the item publicly viewable (i.e., available on the World Wide Web). The latter option allows you to share an item with the participants of another site.
To allow people outside your site to see an item in your Resources:
My Workspaceto access your personal items, or click a course or project site tab to access items there.
