Any way to make a picture stick/bind to a cell in Excel.

The handheld auditing program we use exports the data, including photos to
excel fine, and places the picture over the cell intended, top and left. I
know how to resize it to the size of the cell, but want to make it a bit
smaller than the cell and centre it on the cell to give a small border of
white space around it. I can make it smaller than the cell, but its still
top and left aligned to the cell. the only alignment adjustments I can find
work in relation to the sheet, and not to a cell?

Working in Excel 2000 (that's what my users have)

Thanks
