Browser = Internet Explorer or FireFox, etc ......
I have no idea what a browser is. Bet you didn't know anyone was that computer illiterate.
I'm married to such a person.
Since you don't know then it is probably Internet Explorer. Right click on the picture. Then click on "Save Picture As ..." Another small window will open up that is titled "Save Picture". At the top of that window you will see a box that probably has "My Documents" in it. Left click on the little diamond next to that box. You should now see a menu. Click on the "My Documents" that is in that menu in order to open that folder. Look down until you see the "My Pictures" folder and left click on it. Now all you have to do is click on the "Save" button toward the lower right hand side.
