Variable width is a local variable. You can't get its value from outside SP. Either change your procedure to a function returning image width or add a second out parameter:
CREATE OR REPLACE PROCEDURE get_width (
img_id IN arm_photos.id%TYPE,width OUT INTEGER
AS
image ORDSYS.ORDImage;
BEGIN
SELECT p.image INTO image FROM arm_photos p
WHERE p.id = img_id;
-- Get the image width:
width := image.getWidth();
DBMS_OUTPUT.PUT_LINE('Width is ' || width);
COMMIT;
END;SY.
