Is it possible to publicly share an image map service hosted in enterprise (inward facing, behind a firewall) using an AGOL-Enterprise collaboration? I have successfully set up the collaboration, and I have succussefully shared features publicly. However, I am unable to do the same with imagery--all collaborated service work within AGOL when on our network, including the image service. When outside of the firewall, the image service does not work while the feature services do.
