The Image component lets you embed images into reports. Images can be dragged from a local computer, shared drive, webpage, or the Image Management Tool as files onto reports. They can also be pulled as binary data from a datasource. If no Key is associated with the image component, the dropped image will be used. If the Key does not link to a valid image, no image will be shown. The image displayed in the Report Designer is a placeholder. It will be replaced with the image associated with the image's Key when the report is generated or previewed.
In the image component's Property Inspector, you can drag a parameter or a datasource column from the Key Browser into the Key field. The Data Key can resolve to a byte array, such as an image retrieved from a database, or a URL that points to an image on the web, or an image file on a disk. Remember that reports are generated on the Gateway, so the image source needs to be accessible from the Gateway computer.
Keychain Expressions can not be used in the data key, but the Key can be a parameter or datasource that dynamically constructs a path to an image. This allows you to easily change images in reports without changing the image component.
