Click on the image on the server, then go to your top menu bar and see if there is something called Get Info under one of the dropdowns.
What ftp client are you using? Have you tried doing a google search on how to change permissions on a file using that client?
This is what you have in your source code for the image:
HTML Code:
<img src="images/misc/tSSLOGO" border="0" alt="Rooms" />
You need to put .jpeg at the end of the image name:
HTML Code:
<img src="images/misc/tSSLOGO.jpeg" border="0" alt="Rooms" />
It still won't work until you fix the permissions on the image.
