The partnumber enquiry can display pictures of partnumbers. Double-click on the picture's thumbnail to open the file:
Picture files can be in any folder. The default folder is \HERSCHEL\PICTURES.
Note the picture files can actually be any type of file, not just pictures. For example, you could have a Word document as a partnumber's picture file. One approach used by some Herschel users is to create a multi-document PDF containing full details of the partnumber, and to set this file of data as the partnumber's picture file - Herschel will open it in your default PDF viewer.
