Latency in display images

[vkEE]

Hi, I just started a few days ago at my new work place. One issue, my first issue, I am researching on - we have the main company web site on main domain, all the images are located in sub domain. It is a heavy images driven web site. On the IE Explorer, after you load the web site, and hit the key F12, you are able to run some statistics on the current web page. There is a latency in loading the images, although the image is ready to be loaded. Any thoughts on the latency? Do you think it is because on running on sub-domain? When I plug in the URL directly to the image, the response time is much faster, while the main web site's response time is almost double the time. Also the received size is not the same on both images, once from the main web site, and once from the plugging in the url directly. Thank you!!

Where is the sub-domain hosted - on the same server with the main domain? What is "plug in the URL directly to the image" - I do not understand that.

How are the site loading the images? Did you see that code? It is very strange that the image does not have the same size.

I think this has to do with the fact that some browsers first load what they see as 'the main content' - e.g. if your site is hosted on 'mydomain.com' and your images are hosted on 'img.mydomain.com' the browser loads content residing on 'mydomain.com' first because you entered this URL and the browser assumes that you want to see this content before loading the other content from a subdomain. Another cause are possibly very large images - Their transmission via network is slower than the site's content and therefore they are displayed after the site has loaded (just because they are not completly transmitted yet). cheers, Marco
