“How to” display picture from file in Item Picture Page


Below a short procedure to visualize a linked picture from a picture file (example file with “.GIF” extension) into the “Item Picture Page”.

The System load the image file in a BLOB field and after displays it on the picture page; at the close of the page the image is deleted from the item table in order to lighten the System; same procedure can be used in reports and can also be used in old versions of NAV… in this case NAV 2013.
