IEG scripts allow you to specify images to use for both your sections (in the navigation panel to the left of a page, by default) and pages (in the page title area for the page), and also comes with some images which are built in to the system (like the various person images used in person tabs, etc.). All of these images must be stored in the resource store so that new images can be added and existing ones updated without having to rebuild and re-deploy your application. When uploading an image resource, set the "Content Type" appropriately for the image (e.g., image/png, image/gif etc.) and leave the "Content Disposition" field empty.
