Thank you for the detailed instructions. What I had done was to print screen on word document; place the callout; print screen again on word and that would integrate the callout unto the screen picture. The only thing I did not like is that Print Screen does not seem to be an exact duplicate but a picture of the screen, something similar to a photocopy and, as all copies, quality is lost. If you use it twice you are making a copy of the copy. What I was trying to prevent was using print screen twice. what I really need is to embed the callout on the original print screen picture. If my impression that it is a photocopy of a photocopy is correct, then the situation worsens when I use a snag tool to select part of the image with the callout in order not to use the whole screen on my fianl workarea. That becomes a third generation copy! But mayber my problem was in using Word instead of Paint in the first place. I'lll try it the same procedure with Paint to see if the third generation does not lose quality. I'll let you know.
Is there any way, after doing the original print screen, to embed the callout and save the image combination on a single fix image without resorting to print screen again?
