Why can it happen that the large image (30 Kb) takes 3 or 4 seconds to show up?
Generally the site goes fast. I can go from section to section without delay. But every time I click on an image there seems to be a constant delay of several seconds. I see on Firebug that it's calling ajax.php, which seems to include many other files. Is it that the code is taking a long time to execute? Or something misconfigured on my server? Why is there PHP code running at all to show a larger image? Isn't JavaScript enough?
Thanks!
