A Picture object. If you assign a picture located in a worksheet other than the current worksheet, an exception is raised.
An image in a worksheet is a Picture object, which is a descendant of the Shape interface. All images in a current worksheet are contained in the ShapeCollection accessible via the Worksheet.Shapes property. To specify a picture selected in the worksheet, use the SelectedPicture or Worksheet.SelectedShape property.
You can also select multiple shapes in the worksheet simultaneously. To get or set a list of shapes selected in the worksheet, use the Worksheet.GetSelectedShapes or Worksheet.SetSelectedShapes method.
The SelectedPicture, SelectedShape, GetSelectedShapes and SetSelectedShapes members of the SpreadsheetControl or SpreadsheetControl object allow you to select shapes in the worksheet that is currently active in the control.
