public class D2WDisplayImage
extends D2WStatelessComponent

The D2WDisplayImage class is a property-level component that displays an image served from the database. Be sure the attribute is in an image format such as GIF or JPEG.

Property-level components are not accessed programmatically. Instead, you use the Web Assistant to choose the property-level component that Direct to Web uses to display a property on a particular entity and task page.

If you want to create a property-level component to display a property, use D2WCustomComponent.
