First you will need to add the elusive "camera" icon to one of your
toolbars. It is found under the tools section.
1) Place a picture onto a spreadsheet.
2) Highlight the cell or range of sells you want to be included in the
camera snapshot - the range of cells containing your picture.
3) Click the camera button.
4) Go to a different spreadsheet and select the range to paste your
linked camera picture.
Anytime you update the original embeded picture...the camera picture
will also update.
