Inserting images as background for OpenOffice Calc graphs

(Thanks to Eduardo David Jr. for tip.)

In verbatim, Ed's advice:

"1.)Click the plot ONCE
2.)Choose Area (see attached image)

3.)Go to Bitmaps tab, then choose Import
4.)Select the image
5.)Double click the plot then choose Chart Area
6.)Under the Area tab, choose Bitmap
The imported image should appear in the list :D"
