The Jet NL("Picture") function loads an image from a BLOB field in Dynamics NAV or from a file.
Examples of the NL(Picture) function
Retrieving an Image from a Dynamics NAV BLOB Field
To use a picture that is stored as a BLOB in Dynamics NAV, enter the Table, Field, and Filter parameters that will select the correct BLOB. You can enter "Height=" and "Width=" in the filter fields with numbers in the corresponding filters to set the height and width of the picture. If you do not enter sizing specifications, Excel will choose a default size for the picture.
Retrieving an Image from a File
To load an image (.bmp, .jpg, .jpeg, .png) from a file, use an NL function with "Picture" in the What parameter, leave the Table parameter blank, and put the file name in the Field parameter.
