Although it is really easy to paste a graphic from a Web page, the
recommended procedure is to right-click on the graphic and use Save Picture
As. Save it to My Pictures or some other easily found location, then use
Insert | Picture | From File to put it in your document. I think you'll find
that this procedure will help.

In recent versions of Word, you'll find that pictures are inserted/pasted as
In Line With Text by default. If you want to be able to move them freely,
and have text wrap around them, you need to change the wrapping to some
other style. When you click on the picture, the Picture toolbar will be
displayed. Click on the Text Wrapping button (dog icon) to get a menu of
wrapping options.
