public class D2WDisplayImageFromPath
extends D2WStatelessComponent

The D2WDisplayImageFromPath class is a property-level component that displays an image whose name is stored in the attribute. The image must be a resource in your application or the framework that you specify in the Web Assistant.

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.
