In summary, Bruce was right when he suggested, as also done by Claus,
and written in Prof. Hans Lehmann's book here:
https://gambas-buch.de/doku.php?id=k22:k22.4:k22.4.12
:start#klasse_blob_gbdb
to use Base64.

You can memorize it like this:

    sPath = "img" &/ Lower(aSurNames[i]) & ".png"
    hResult!image = Base64(File.Load(sPath))

and you can read it like this:

    hImage = Image.FromString(FromBase64(DataControl6.Value))
    PictureBox1.Image = hImage

Thanks again to everyone who helped me understand.
