[Plugin: NextGEN Gallery] Having one image in galery shows [show in slideshow]

I’m using version 2.3.2 of WordPress with NextGen gallery version 0.98.

When I create a gallery with only one photo and add the gallery to an article I’ve found it still states [show as slideshow] above the image as can be seen at this link https://worldramblers.com/the-durbar-square-of-patan/

As there’s only one image in the gallery I feel there isn’t the need to show the [show as slideshow] text.

Would it be possible to make an enhancement to the code to perhaps detect how many images are in a gallery and if there’s only one to not display the [show as slideshow] text ?????
