In PL/SQL you can use this procedure to save image in directory:

CREATE OR REPLACE PROCEDURE SaveFile(
   FileContent IN OUT NOCOPY BLOB
   , FolderName IN VARCHAR2
   , FileName IN VARCHAR2)
IS

    BUFFER RAW(1024);
    OFFSET PLS_INTEGER := 1;
    FileLength PLS_INTEGER;
    amount PLS_INTEGER := 1024;
    fhandle UTL_FILE.FILE_TYPE;

BEGIN

    FileLength := DBMS_LOB.GETLENGTH(FileContent);
    fhandle := UTL_FILE.FOPEN(FolderName, FileName, 'wb');          
    LOOP
        EXIT WHEN OFFSET > FileLength;
        DBMS_LOB.READ(FileContent, amount, OFFSET, BUFFER);
        UTL_FILE.PUT_RAW(fhandle, BUFFER, TRUE);
        OFFSET := OFFSET + amount;
    END LOOP;
    UTL_FILE.FCLOSE (fhandle);

EXCEPTION 
    WHEN OTHERS THEN
        IF UTL_FILE.IS_OPEN(fhandle) THEN
            UTL_FILE.FCLOSE(fhandle);
        END IF;
    RAISE;

END SaveFile;
