Snapshot updating over network reference

[squallxgamer]

I have a workbook that I am trying to reference another workbook on the network with a dynamic snapshot. I notice that it will not update unless I open the source document. How would I force the snapshot to update upon opening? I am using snapshot because the sheet has pictures on it that I want included. I checked the trust center and everything seems to be in order.

Your help is appreciated.

thank you!
