1. Double click with the left button on the picture you want to download - this takes you to the Full Size Picture.

2. Click once with the right button on the Full Size Picture and you will get a Menu List.

3. Click on  "Save Picture As..."

4. You will get a Dialogue Box (titled "Save Picture") that has at the top, an area titled "Save in:".  This is the Folder on your computer  where the picture will be when you save it .  You can change to another Folder by clicking on the yellow folder with the bent arrow pointing up,  until you find the folder you want to put your picture.  I believe the default Folder is "My Pictures".

5. At the bottom of the Dialogue box is an area titled "File name:" with a file name already in it.  You probably will want to change the file name and all you have to do is left click in the white area outside of the file name - delete the file name by back spacing and type in a new name.

6. Click on the "Save" button and the picture is saved to the folder identified at the top of the Dialogue Box with the name in the area at the bottom of the Dialogue Box.
