Modifying the prettyPhoto slider using shortcode or child theme?

Hello all,

Sorry if already answered, I did look but could not find solution….

I have the BT (business theme, responsive) installed.

I want to change the autoplay of the slider when you click on the gallery image from the listing page.

Have tried changing values in the shortcode class file, and also tried changing values in the prettyPhoto js file. But neither file value settings seemed to make any difference….

So was wondering if we can pass the option vis the shortcodes like:
[IMAGES autoplay=false, autoplay_slideshow=false, slideshow=false, slideshow=10000]

I assume it should be possible this way, as looking thorough the files you can pass variables via shortcode…

Can anyone tell me what variables if any, can be passed via the [IMAGES] shortcode?

Looked on premiumpress documents pages, but this shortcode is missing descriptions?!

Any help appreciated, and hope my explanation is clear!

I saw others have asked this question, but no real answer has been provided in forums (from what I can see).

All the best !
