Access Detection

[sojourner]

How do sites like Corbis and Blue Mountain detect that a "card" has been accessed and how do they know which of the recipients has accessed it?

Hi soujourner,

You shouldn't post the same question in more that one forum. Either this or the thread in javascript forum needs to be closed -- so, take your pick. If I see no response within 24 hours. I'll close the javascript thread. :)

You can close the one in Javascript.
Thanks.
