Products can each have multiple images stored against them.
The actual Image files are stored in Infusion \ Data \ Images \ Products \ XXX so they can be backed up and restored easily; and can be retrieved for reports / layouts.
The IMAGE column in the PRODUCTS table - stores the name of the first image file name - inside quotes. This may or may not be the default image for the product.
All of the links to the images are stored in the table DOCLINKS. The product code is stored in the ID column. The records for PRODUCTS have STK in the MODULE column, and the TYPE column is IMG. The DESC column will have the name which the user can assign to the image. The actual file name is stored in the column FILENAME - with no quotes.
In the SYSTEM table the Charval field also needs to point to the relevant file path eg DATA\Images\Products
