The symptom of being able to get half of a page loaded but no more is almost 
certainly a network problem. Determining just whose network the problem is 
in requires significant technical expertise.

The LUG Gallery server computer is in Redwood City, California. In order to 
connect to it you must use a network path that joins your computer with that 
location. It will be a different network path than the one joining your 
computer with Miami or London or Antofagasta. Typically there are between 15 
and 20 network links between your computer and any server, and it only takes 
one of them being overloaded or misconfigured to cause the problems that you 
describe.

Just now I did a trace from the LUG Gallery server to the computer from 
which you sent your email (on a Mindspring cable network connection via 
Melbourne, Florida USA). It passed through
        Mindspring in Orlando
        Roadrunner in Daytona Beach
        Roadrunner in Orlando (yes, it went from Orlando to
           Daytona Beach and back to Orlando)
        Level3 in Orlando       
        Level3 in Atlanta
        Level3 in Denver
        Level3 in San Jose, California
        Level3 in Palo Alto, California
        Level3 in San Francisco, California
        My server in Redwood City, California

There were dozens of hops inside Roadrunner that I didn't enumerate 
directly. Looking at this trace and at the level of dither I see in 
Roadrunner in the trace, I'd bet a couple of beers that there's some sort of 
network issue in the junction between Roadrunner and Level3 in Orlando that 
is the root cause of your difficulty in looking at the LUG Gallery.
