inserting image in screenplay

My goal is to insert a jpeg image as part of the ‘action’ discussion.

At the beginning of an ‘action’ format line, i select edit>insert image. image size is 400w x 300h pixels.
The image is inserted, but the height of the image overlays previous text.

As a work around, i add several empty lines above the insertion point to lower the image until it fits below previous text.
Doing this, apparently, makes the corkboard scenes blank, although if i mouse over an ‘index card’ some text appears.

Is there a correct way to insert images into a screenplay to avoid the problem and workaround i described?
