I've just been asked to do a complete revamp of a site built by somebody else. I've been taking a look to see what's there, and found a (to me) very odd construction. There are a series of small images, which one clicks for the larger image - except that it doesn't work like that and I've never seen this technique anywhere. The HTML reads
The .html file referenced in the <img> tag contains
<meta http-equiv="refresh" content="0;url=http://**.***.***.**/" />
followed by a vast array of numbers, in groups of three, commented out in the HTML. There is a separate file for each image, but the content is identical, as far as I can see.
Clicking the small image opens the URL in a new window. There are no images, just a series of links. I've checked the IP address of the URL in hpHosts Online, and it's associated with a long list of dodgy sites.
My question is basically: was this ever a genuine method to display a large image, or has the site been hacked at some point, or what?
