When you design a Notes application, you have the option to imbedded images as resources with the Lotus Designer. Below you see a snapshot of the Image Resources in the mail database:
Traditionally the Image Resources are used to store design elements of the database.
By importing any image into a Notes database as an image resource, the image can be referenced by the rich text field instead of embedded. The image itself, will therefore not be stored in the rich text field, only a reference to the image resource.
The real benefit of storing the image as a resource, is that the image can be shown in ordinary Notes views. II2LN automatically take care about all the difficult parts for you!
