Is it possible to count outgoing visitors of my site?

Hello,

I have a website in which I putted reviews of different service providers. I had putted this link in image foam. Now I want to check how many visitors are diverting from my site to my providers from particular image. Because now I have to believe in what they say. And I have a doubt that some of them are cheating me. So is it possible to count outgoing visitors of my site? Please reply.

Thanks in advance.

What you have to do in order to count the people who click those links is to have the links call a script on the server that does the counting and which then transfers the person to the destination site. It would be invisible to the users unless they check the URL they are clicking on and see that it goes to the count script and not to the final destination.
