QUESTION:
How can I assign headers to OP3 pictures so that the pictures are listed in the table of contents?

ANSWER:
In ProTool V5.2 / SP2 you can no longer assign headers to OP3 pictures. If you still want to assign a header to a picture so that it is displayed in the table of contents, then please proceed as follows:
Configure an empty picture for an OP7 and give this picture a header. Then copy it into an OP3 project. Now you can no longer change the header.

Note:
With ProTool V6, headers can be assigned.
