The contents, syntax and semantics of the Stock List file as well as instructions on manually editing the file itself are found in the section entitled "Stock List File" in this help document.
The most important visual depiction of the parts of the Stock List file is the Stock List Window. This provides not only a way to view the relevant data about the pictures, but also serves as an instrument to edit the picture file and the properties of the pictures themselves.
Detailed information about the individual functions is available in the chapter entitled Stock List File. Alternately, clicking on the section of interest will open the help file directly.
The Stock List can be opened from the Configuration Window via the menu bar commands Functions | Open Stock List or by clicking on the button labelled Stock List in the Configuration Window itself.
