I can think of several way depending on how you have other things setup and where you are pulling the data from. That said the easiest thing I can think of and have doen it several times myself is to roll-your-own output filter.
So you would do everything the same as you have it, except you would add the output filter to your placeholder
adding rtrim and then creating a snippet called "rtrim" would then allow you to do the following.
$input = $modx->getOption('input',$scriptProperties,'');
return rtrim($input,',');
This would then strip the right most char off the end if it is a comma

This works great, thanks for looking.
I think I have some timing issues now, js executing before the gallery placeholder has fully loaded. I'm not sure though, I think I'll start another thread.
Thanks
It could not be the gallery itself unless you are executing the gallery through an external ajax call. The gallery placeholder along with anything MODX related is all back-end (ie: server) processes.
Think of MODX as a big HTML generator and nothing gets sent to the browser until the HTML page is completely build. Then all HTML for the given DOM is delivered all at once. Thus all of the Gallery is in place.
This is not to say that all images will be there because images are then a separate request after the HTML is delivered.

Ah thanks again, that hopefully eliminates my theory. The js which the gallery placeholder feeds the paths into is inline so as you say this should all be completed before reaching the browser.
I've discovered this problem only occurs in Chrome so it's possibly not directly related.
Much appreciated, cheers
