Simple dear



----------you can read images one by one and insert into the database-----------------

:CONTROL.file_path := get_file_name('C:\MY_PIC', NULL, 
    'JPEG Image (*.JPG,*.JPEG,*.JPE,*.JFIF)|*.JPG|Bitmap Image (*.bmp)|*.bmp|GIF Image (*.GIF)|*.GIF|TIFF Files (*.tif)|*.tif|All Files (*.*)|*.*|', NULL);

DECLARE
	image_path VARCHAR2(200);
	image_extension VARCHAR2(3);
BEGIN
	image_path := :CONTROL.file_path;
	image_extension := SUBSTR(:CONTROL.file_path, -3);
	READ_IMAGE_FILE(:CONTROL.file_path, image_extension, 'MAIN.IMG');

END;
----------------------------------------------------------------------------


OR if you wanted saved complete directory in same time then follow this

CREATE OR REPLACE DIRECTORY images AS 'C:\MY_PIC';

Next we create a table to hold the BLOB.

CREATE TABLE tab1 (
id NUMBER,
blob_data BLOB
);

We import the file into a BLOB datatype and insert it into the table.

DECLARE
   l_bfile BFILE;
   l_blob BLOB;
BEGIN
   INSERT INTO tab1 (id, clob_data)
          VALUES (1, empty_blob())
   RETURN clob_data INTO l_blob;

          l_bfile := BFILENAME('IMAGES', 'mughals.gif');
          DBMS_LOB.fileopen(l_bfile, Dbms_Lob.File_Readonly);
          DBMS_LOB.loadfromfile(l_blob, l_bfile, DBMS_LOB.getlength(l_bfile));
          DBMS_LOB.fileclose(l_bfile);

COMMIT;
END;
