Thread: Image display problem on JFrame...Can any1 help?????'

I have created a project in netbeans'
It has a main file (input_image.java).
Using JFileChooser, it browses for an image file on computer, and displays it on the frame.....'
'
I want, whenever the mouse is rolled over the image, another JFrame (msgbox_full_image.java) should open displaying the larger preview of the same image....'
And when mouse is exited from the image, tha JFrame showing larger preview should close...'
'
I have succeeded in displaying and closing the JFrame by using mouse events (mouseEntered and mouseExited)'
'
Now....the main problem'
-----------The image is not displayed on the JFrame (msgbox_full_image.java)-----------'
'
'
(Attachment of project also attached )'
