How can i have a picture as a background and have coordinate on that picture using Java ?
i have done the browse and display picture function in my laptop, but now i don know how can i set a coordinate for
that picture ? However, that coordinate should be invisible to user , so when mouse move over the picture ,it shows the coordinate .
That is really difficult for me as i'm newbie in java .... Someone please help me.......

You will need a MouseMotionListener. On the mouseMoved you can get the mouse coordinates and display them as a tooltip.
