Adding a background image to the spreadsheet
To add a background image to an Excel spreadsheet, on the Page Layout tab, in the Page Setup group, choose Background:
Excel displays a dialog box that enables you to choose a graphics file.
When you locate a file, click OK. Excel tiles the graphic across your spreadsheet. You also want to turn off the gridline display because the gridlines show through the graphic.
Some backgrounds make viewing text difficult, so you may want to use a solid background color for cells that contain text.
The graphic background on a spreadsheet is for on-screen display only - it isn't printed when you print the spreadsheet.
