RDLC doesn't show external images from other computer

I have a program which is network to multiple users. The main server/database and folder is in Pc1. However, when generating the rdlc report in Pc2, it shows "An error occured during local report processing. Report 'Report1' contains external images. The Enable ExternalImages Property has not been set for this report."

I have already set source = External , Value = "file:///" + Fields!filepath.Value and EnableExternalImages=True but still doesn't show any images.
