Are you saying you want to show a picture that is NOT saved in nav?
Their is a BLOB field in the company info table #29 Picture.
As above to show a picture stored in a BLOB field in nav you use calcfields to show the pic.
If you have an outside pic you can use the toolbox to add am IMAGE box.
Under Properties->Bitmap you would put your path ie. c:\MyPic.BMP
Another way is to import on the fly, say all your item pics are saved outside of nav.
you can create a report using ITEM as the dataitem (note my item ics are saved using the Item number as it's name.)
OnAfterGetRecord()
IF EXISTS ('C:\YourPictureFolder\'+"No."+'.BMP')
THEN
Picture.IMPORT('C:\YourPictureFolder\'+"No."+'.BMP',FALSE);
CALCFIELDS(Picture);
