How to Dynamically resize the HTML pane from the script ?

Hi all.

I do a small toolbar HTML-panel to the PS CC2015. One of the buttons needs to show pictures in a particular folder. Not to do from the toolbar is the large size, I decided that it would be better to resize the panel:height and the div:height which will be shown pictures.

It is possible to make resizing of the panel (shift - increase or decrease the height to 500 pixels) at the touch of a button on the main panel ?
