Pictures not showing on sites

[mulle83]

Hi all

First post on here, so please bare with me

But pictures on one of the sites I use most, all of a sudden stopped showing on the front page. (www.port-vale.co.uk).
I updated flash and followed all their instructions, to get non showing pictures to show up. Little did it work.
I flushed my cache, still no succes.

My system is 10.13.6 (beta) and my Safari is 11.1.2

So I was wondering if anyone on here, has an idea as to what I can do to get it to display correctly?

I have attached a picture, of how the page displays on my iMac.
