Hi! Thanks for your help! The code besh posted works great, I use it with addClass because that's the easiest way to handle it (since the behaviour is already set for the image-link & I only had to add the .hovered-class).
To Charles: Thanks for your effort. But there is the class "email" in the markup, as well as two links: One in the div.memberpic, one in the div.memberinfo (which includes the a.email). The hover on the image is completely done by CSS, there's no need for any javascript :) (For further info see the tutorial-link in my first post) Anyway, thanks for your effort! Greetings, Jayzon
