I notice when I place my cursor over a person's name, a picture of their blog pops up. I see this feature comes from snapshot.com. I signed up for it. But I got lost when it came time copy and paste the code. I don't know where to paste the code. Then they have "quick" install for wordpress bloggers. That didn't work for me because it requires activation of plug-ins. In sum, how can I activate that preview feature for my blog?
