Summary:
When only one image in slideshow, dont show controls, since its pointing back to index (#) if clicked
Detailed Description:
If you include the slideshow on a subpage, and only have one image in the
slider. The navigation buttons will appear, even if theres nothing to go
next/prev. Beacuse of this the href will get "#" and point back to index if
clicked.
Solution: {if $show.st_showcontrols && $items|@count>1}
