Yes, thumbs are currently tn_NAME.jpg - against NAME.jpg
Would it be a case of setting ID=NAME.jpg
and then setting:
var image = images[$(this).attr('ID')];
edit:.... thinking - could this just be: var image = $(this).attr('ID');
I will try this.
@DanInMa - I will also try using the bg tag
PS - the js I have is from a background changer I found. Can it be simplified?
I think I am almost there. Thank you.
