Topic: nav bar appearing on rollover

Is it possible to make nav bar appearing on image ?
I mean that slideshow size is 900x600 and when we click on middle of the image, a control bar appears for prev, next ,play/pause, fullscreen and thumbnail icon.
if we click on thumbnail icon nav bar (filmstrip) appears over the bottom of the image.
no idea for caption, perhaps a extra icon in control bar to make caption on/off over the top part of image.

best regards
