Hi all!
I have had this same problem but it was not with Norton Firewall. I'm not sure what the problem is, but some computers I have (two at home) could access my website and all the pictures would show, and some computers (one at home, one at work) would not allow the pictures to show. Like I said, none are running Norton Firewall.
So, I did some research and found a site that will produce the code needed, but with 4 different configurations. I have tried all four, and found that #2 works for me and none of the others do. The other 3 configs either enabled the pics to show up on my site AND can be linked to, or not show up on my site and cannot be linked to.
This link also has a "tester" to test links, which is very helpful.
Anyway, here is the link to the site:

Hope this helps someone else out there!

NOTE: On the "tester" I have found that if you first test a pic it may show up, but if you hit refresh, it will not show up and will stay that way.
