Anyway found a fix/solution.
Logged into the server and downloaded the images I wanted into the images folder. Then on the page I edited the source code and changed what it enters
<img width="200" height="50" alt="wynnstay.png" src="http://ostickets/helpdesk/file.php?key=yicwxqo3dmnjhclxirdzgrpxljt7rrqu&expires=1485388800&signature=0cd9c75022866fe708bac4a35557e6b5e8b95ee4">
to
<img src="/helpdesk/images/xxxxxxxx.png> etc and that works.
Not sure why it trying to add images with that code lol
