There are a lot of graphics applications in the world. Some of them allow you to browse the contents of an entire folder. But you have to start the program to browse and view any individual file. In the latest Windows versions Explorer can be switched into the Thumbnail view too. That is fine. But it can be a pain, if you are looking for one small image or just have to look at couple of files. Instant ThumbView gives you a solution. It is an instant image viewer that displays thumbnail (reduced picture), of selected image in a popup window next to the mouse pointer. It supports a lot of popular image file formats, including BMP, GIF, JPEG, PNG, WMF, ART, DIB, etc.
As Instant ThumbView is a Windows Explorer extension, it is always ready and available to use. To invoke it, just toggle the SCROLL LOCK indicator on, and then hover an image file with your mouse in the Explorer's window.
You will see the tooltip saying 'Extracting Thumbnail...', and then the image thumbnail should be displayed as shown on the screenshot.
