I am running Office 2000 in WinXP.

I have a need to display several dozen .jpg files, each 10 megs or so in
size in a workbook, with 4 or 5 of them accessable from each worksheet.
Placing each entire picture into the workbook, it becomes unwieldy in size.
I have decided to place buttons on each worsheet with thumbnails of the
picture to be displayed on the button, so that when the button is pressed,
the full size file is displayed.

The following VBA code works:

Dim RetVal
RetVal = Shell("rundll32.exe
C:\WINDOWS\system32\shimgvw.dll,ImageView_Fullscre en
picture_name_and_path.jpg", 1)

This displays the full size picture in Windows picture and fax viewer. It is
a solution I can live with. But what I really want to do is to display the
picture using whatever the default .jpg viewer is for that computer just as
if the picture file was double clicked.

There must be some function such as "show using default pic.jpg"

If this is not clear, I can further explain.

Thanks
