opening image files

I want to open image files (PDF, DWG, JPG) with a command button on a form.
:confused:

to be shown in your own form?
if so you would need some kind of control to show those or find out how the filetypes work, but I think that's a lot of work!

No, they could open up in a new window

If the user already has something capable of viewing them on their machine (such as Acrobat for PDF's) then you could shell to that...
