I have a spreadsheet which was created by a C# application.
There are images (pasted jpegs from code) on a number of worksheets in
the workbook.

When I open the spreadsheet in Excel I can't select, move, resize, etc
these images.
I also notice that all the menu items under Insert/Picture are disabled.

The cells don't appear to be locked and there are no permissions
(unrestricted access) to this Shared workbook.

All the text, numbers and formulas are selectable and editable.

anybody have any idea what's going on?
thanks
mike
