Custom thumbnail images for slideshow?

Hello,

I’m currently adding in a slideshow element to my website and I’m wondering if it’s possible to use different images for the previews of the thumbnails?

(at the moment they look quite busy so I’m wanting to give them some more simplistic icon images instead of the generated preview)

There doesn’t seem to be much customization capability for this widget so maybe it could be done via some code hopefully?

Any help would be greatly appreciated!

Thank you

well, in generall this should be possible with custom code…
But I wouldn´t recommend to try this out if you aren´t fluent in css/jquery/js
