I have created a database table which store text datatype, so now i need to have 4 path files to reach the user selected images....

set the Userdata property of the subplot axes to hold the information. Then when the user interacts with one of the subplot objects, user ancestor() with the 'axes' request to find the axes from the object, then get() the Userdata property to get the path.

thanks for the answer sir.... does the userdata property hold the file information automatically for the images displayed in the subplots or do i need to set the information manually....
