    g2D.drawImage(bi, dx, dy, scale*image.getWidth(this), scale*image.getHeight(this), this);
    So, as a hint i can tell you, when you move the image to some place, get the coordinates and place in the above line so that your image drawing must be generic everytime, not hard coded. As above mentioned line.
    I understand that you are telling me not to use hard coded parameters like dx and dy. But logically lastx and lasty will be the last position where the image is, but if I use lastx and lasty in the drawImage function, it still jumps.

    It jumps coz the size of image is too large and it takes your image to the mouse position whenever you try to drag it.
    Hint: Let mouse drag the image if mouse is inside the image coordinates.
