As Greg asked, please explain what the Next Button is to achieve then we can give you an answer

Alternatively, select Page Layout, Background, select a picture from your picture file, click insert. This fills the screen with continious pictures. Then paste your data range on top of the pictures.

The only way to "cut off" the cells is to hide them. You can never really get rid of them.

So any row or column you don't want to see, select them and right click and then click on Hide.

As for the Next button.. exactly what do you want to do? Click it and go to the next sheet in the workbook?

Perhaps you are used to Word. Why not insert your excel data as an Object in a word document. Then you can format you page as you wish. You can also insert Excel objects into PowerPoint.
