How can I avoid Google Image Search traffic? Is it possible?

[Oxydada]

Hi there

Since about 3 days I'm having huge loads of traffic coming from Google Image Search - I have an entertainment blog, so half my content are pictures, half text and news.
This kind of traffic is really hurting my stats: bounce rate now is 25% up and my Adsense CTR is down 40% - people just look at the picture for just one second and they're gone.
My blog is optimized and it has good content and used to have a nice bounce rate.

Is there any way to avoid this traffic? Is is possible to 'opt-out' from Image Search?
Any trick to avoid my images being indexed?
What about the nofollow tag on pictures? Would that work?

Thanks in advance and please excuse my English.

Can't you just disallow the Google Image bot in your robots.txt?

Something like (I think):

User-agent: Googlebot-Image
Disallow: /

Do not reject such traffic i feel.

What you can do is have a frame break out script where if the user clicks on your image, it redirects him to the actual content page.

It takes a long time to be included or excluded from google image index

If you're sure you don't want Image Search traffic, you could also use robots.txt to disallow the /images/ folder altogether. Either do it just for googlebot, or probably better in your situation, make it a universal request for all bots.

User-agent: *
Disallow: /images/
