I can no longer find the picture box in my DFMA software. How can I bring it back?

You have probably changed the display of the Picture box.

In DFA, check the View characteristics of the Questions Panel view you are using. (View->Questions Panel->Customize…) In the dialog see that Picture is checked in the list of Questions boxes shown.

In DFM Concurrent Costing, choose Tools->Window Layout. In the dialog in the Other box, see that the Show picture box is checked.

In DFE, pictures are only available in the Notepad. Choose Notepad from the Show menu.
