Since setting up the RBK50 Orbi, my emails have not been displaying images. Is this a network issue or a setting?

One of the reasons that can cause such strange -unjustifiable- issue is having double NAT in your network. If your ISP modem is acting as a router and does NATing on the incoming WAN traffic then this can cause different issues since Orbi is also doing NATing. You need to check if you have double NAT.
Please open a Command Prompt on any computer attached to Orbi and type:
> tracert 8.8.8.8 (or traceroute 8.8.8.8 if you're using a Mac computer)
1. If you see two private IP addresses listed in the first two hops then you have double NAT. Please check the model of your ISP modem and if you have a manual for it.
2. If you see only one private address and the second hop shows a public address, then you’re all good and we need then to troubleshoot further to find the root cause of the issue,
