[Plugin: NextGEN Gallery] Highslide: Caption, Next, Pres

Hi,
i use NGG with Highslide Plugin. When i use the Highslide Plugin direct (withot NGG) this way:
<highslide image="/wp-content/gallery/nyc/IMG_5492.JPG" thumbnail="/wp-content/gallery/nyc/thumbs/thumbs_IMG_5707.jpg" altdesc="Dies ist ein Test" captiontext="HUHUHUHU" />
it shows the image (as checked in the highslide settings) correct WITH Caption and Buttons.

But NGG seems to override these Settings, so i dont see any Buttons when using Highslide with NGG. Can u help?

THanks alot
Dennis
