What it does:
Image Toolbar is a clone of one of Internet Explorer's features and provides quick and easy access to a handful of image functions in a highly customisable way.
The toolbar is activated by hovering your mouse cursor over an image. It will be displayed (by default) in the top left hand corner of the image, and allows you to save the image or perform other functions.
Save - You can set this to either prompt you to save or to automatically save to a previously chosen directory.
Copy - Let's you copy the image location or to copy the image (so that you can paste into an editing program).
Print Preview - This button opens a new tab (which is automatically closed afterwards) and switches to Print Preview mode. A handy way to directly print your images.
Image Folder - This allows you to open your designated image folder quickly or change it to another folder.
