Richard, without your design file or a published page, it is difficult, but guess to your problem and remedy is as follows.
The actual link for the second image is https://charliehall.proboards.com/ not http://charliehall.proboards.com/.
I would untick Connect automatically and remove the protocol from the link, leaving charliehall.proboards.com/.
Do this for all the links.
