Could anybody help me, please ?

offset INTEGER;
buf RAW(2000);
BEGIN
/* select the LOB from which to read and return the locator into 'ac' */
SELECT audio_clip INTO ac FROM multimedia_table WHERE id = 1;
/* open the LOB */
DBMS_LOB.OPEN(ac, DBMS_LOB.LOB_READONLY);
/* read the LOB value into 'buf' */
amount := 2000;
offset := 1;
DBMS_LOB.READ(ac, amount, offset, buf);
/* close the LOB */
DBMS_LOB.CLOSE(ac);
END;

You can directly use read_image_file built in to read an image from the clients system directly into a image object. And regarding form server crash, it is no where related to the form u are running. try to invoke forms runtime screen(which is available in forms installed software) and work with it.
And web.show_document cannot be used to open images from client side. As the form server will not recognise the clients file system.
