Two replies - first, to get rid of the menu bars, go to File>>VI properties>>Window appearence, where you customize your window. Also check out Window size (the one riht after Window Appearence).
Second - by default, each new item you add is brought to the front. To control your picture, use the reorder button (that's the rightmost in the row of buttons on the menu bar - the one with the circling arrows). You can select the picture and move it to the back.
