You can use firefox addons which make it easy and then you will be able to get the URL.
What I do is either:
1. Use the Microsoft Snipping Tool. I think that I may have downloaded it - not sure now, or
2. Open the Windows Pictures Library from Start Menu. Close it down to the Taskbar at the bottom of the screen. Open the Adultwork Picture to its viewable size. Leftclick on picture and drag to the picture library on the taskbar. When the picture library opens up full screen then drop the picture into the library where it will remain.
