Pictures on Forms

[4Wile]

I go to Forms, design.
Then go to a Command Button, and Tab for Format. Scroll
to the picture and find the picture for the Command Button.
Click on picture and nothing happens. I just reloaded the
entire system and still nothing...Yesterday it was worked
perfect...I tried two other MDB systems with the same
results. Usually I click on the picture and it shows me
to find other pictures..select one and import..
