You use an image element to store an image file that can
later be referenced on a web page. To create an image element, you
can either add an image element to an authoring template, site area
or content item, or create an image component.
Creating an image component
You create an image component when you want to reuse an
image in multiple places in your website.
Adding an image element to an item
You add an image element to a site area or content item
when you want the image to be used for a specific site area or content
item.
Adding an image element to a template
You add an image element to an authoring template when
you want the image to be used by a set of items that use the same
authoring template.
