I cannot see images on the site anymore.  I have 
not been able to for some months.

I've studied the text in the "Error Message" that 
comes up.  I've added Museum to my list 
of "Trusted Sites" in Internet Explorer.  I've 
tried turning my software firewall entirely off  
when I visit there.

Nothing seems to work.  No images.  No purchases.

Speaking for myself (not necesarily you) I think 
that it might be my hardware firewall.  
Unfortunately, I can't disable the hardware 
firewall by site, only by port.  And since I 
don't know what port Museum is probing, I'm 
pretty much out to sea.

So, I've given up on Museum.
