Maximum PC

I am using Windows 7 Ultimate x64, and I've come across a weird problem that I've never seen before. I have a directory of images, and quite a few of them are not showing up in XnView because when right clicking on them, and selecting properties, it shows "Unblock" and says the images have come from another computer, of course they did, I got them off the Web.

My question is this, because so many are showing this "unblock" issue, is there a way to unblock the whole lot of them at once, instead of doing one at a time, which will take me at least a month or more?
