Using an Image in a Data Report

I'm developing an application to produce 20 different reports. Each one of the reports contains the signature (jpg file) of an elected official, which means every couple of years the image would have to be replaced on the Data Report. I'm using the RptImage control to display the image on report. The file can be saved on the network directory, but it seems the image get embedded into the report during design-time. Is there away to have the Data Report go to a specific path and retrieve the image during run-time (ie., using LoadPicture)? It sure would be a lot easier to replace one file on a server vs. modifying and redistributing the application every couple of years.
