Google indexes all publicly available pages on your site. You should either make your profile pages private and visible only for the site users, or alternatively use robots.txt standard to exclude these pages from the crawling process. In any case, you will end up with all profile pages being excluded from the Google index.

Thanks Denis,

I think i will go with the robot options, i know there is a pattern that you can use on the "Disallow:" but since the url of the image is something like this:

(.*)/MonoSoftware.MonoX.GetImage.axd?git=UserAvatar&entityid=76087154-9f48-4922-8b7f-a19500ab1a06&CacheDuration=600&537204535

i dont know what it would be the best pattern, can you help me with that?

Regards.

What is the path to your profile pages? I would exclude the whole page containing the images, not just the images themselves.
