Page reports can get resources from your file system using file paths, but sometimes resources are preserved in very specific sources, such as a database. With page reports, you can create a custom resource locator to read any resources that might be required by your reports from any location. This walkthrough is based on the Custom Resource Locator sample and illustrates how to load pictures from the user's My Pictures directory.

This walkthrough is split into the following procedures:

Note: Although this walkthrough uses Page reports, but this can be implemented using RDL reports also.
