About Image Content data instances
About  New  Main  History  More...

Purpose

An Image Content data instance provides an alternative to a binary file rule containing an image.

Benefits

Image Content instances provide an alternative to binary file rules, to store images that:

• are widely used across multiple applications
• look the same for all users, and
• are rarely updated.

For example, you can use an Image Content data instance to identify each division in an organization.

Where referenced

Data content image instances are referenced by the contentURL JSP tag, added to an HTML rule or other stream rule:

<pega:contentURL name="ourlogo.gif path="/logos/" classType="Image" />

Each execution of the stream rule generates a once-only hashed URL, if the user meets the security restrictions (if any) recorded on the Main tab. When the user's browser sends this URL to PRPC, the system extracts the image and returns the image to the browser for display.

Category

An Image Content data instance belongs to the Data-Content-Image class. They are part of the Technical category.

Associated RuleSet

When you save an Image Content data instance, if the Associated RuleSet is [none], the system completes this field with a RuleSet from the current application. This association assists with application packaging. You can update the associated RuleSet using the field in the upper right corner of the form. See Identifying parts of rule and data forms.

If there is no RuleSet associated with the data instance (for example, for existing instances not previously associated with a RuleSet), the Associated RuleSet displays [none].
