NOT. I run firewalls and antivirus and usually block all popups but some sites still have stuff imbedded in them. As soon as I clicked on your first photo, some antivirus scanner started running telling me I had some viruses. Funny thing was, it wasn't my antivrus software but an internet site selling it. So I tried it again and got a different popup for something else. These probably run when a non-registered user of Imageshack visits.
