I found it played a bit slow and things took a long while to load, but my useless ISP [Virgin] throttles my connection, even though they make a big deal in their advertising about 'No Limits'. Lying bastards! A shame as my ISP used to be always rated one of the best then they were taken over by one of the worst in the UK [NTL] who were subsequently taken over by Virgin who made NTL look good!! Off topic rant, but my 4M web browing is dial up like a lot of the time.
Image 2 is particularly stunning BTW.
I just timed image load time and it took 35 secs to load a pic. Did I mention I hate my ISP? But then when clicked on, it revealed the larger JPEG [1200x800 + 243K !!] in it's own window immediately. Like John I'd suggest disabling the popup feature as it allows people to nick your images so much more easily.
