Displaying new dialog from a user control

the main form contains panel in displaying user control.

that user control contains button named "start". want open form2 after clicking on start button.

form2 contains picturebox. after clicking on start button creating object of form2

i passing image form2 in constructor , saving image local variable of form2.

then assigning image picturebox's backgroundimage.

after doing form2.showdialog() in start _buttonclicked();

then showdialog throwing exception "parameter not valid" because local image variable becoming null.
