How to use Image tool bar in Internet Explorer

When you hover your mouse over certain1 web page images, a small tool bar will appear towards the top-left corner.

From left to right, there are four buttons -
a. Save, saves the image to your computer,
b. Print, prints the image,
c. E-mail, creates a new e-mail with the image as an attachment and
d. My Pictures, which opens the My Pictures folder on your computer.

Nothing all that new, but it's a handy addition all the same.

There seems to be a limit on which images the tool bar pops up on, possibly connected with the width and height. This would make sense, otherwise it would keep appearing over image buttons and so on when most people will find the tool bar most useful with photographs and other large images.
