Is There An "OSX Preview"-Like App For Windows?

Working on the girlfriends Mac, one of the features about OSX I’ve come to like the most, is the Preview app. It works quite simply: you drag a bunch of files on to the Preview icon, located in the dock. The result, your selected files are added to a “drawer” in a preview window, where you can quickly look through them. This is opposed to, say, Picasa, where you doubleclick an image, and can now scroll through all the pictures in the same folder (which is also cool, I’d just like a way to delimit my images). Additionally, Preview handles many filetypes.

So, is there a similar app for Windows? Or is there a “dropbox” for Picasa, which allows me to preview only a few files in a folder?
