As Bob mentioned, it really depends on what browser you are using and how
you are doing it. Sometimes I find that when I copy out of Firefox, the data
placed on the clipboard is the URL or the alternate text. The workaround I
use is to control+click (or right click if using a two button mouse) and
then select "Copy Image". That should put the image on the clipboard and
then it should paste ok into the Office applications.
