Problem with a filename or path that contains ")" char

[RickenB]

If the filename or the path contains the ")" character, the image doesn't show because the thumb element have the style attribute as this:
<a href="... " style="background-image: url(http://mydomain.com/path/filenamewith).jpg)" ...

This could be resolved adding the ' delimiter before and after the image path:
<a href="... " style="background-image: url('http://mydomain.com/path/filenamewith).jpg')" ...

So you can modify the row 36 with this:
$(this).parents('.sp-wrap').find('.sp-thumbs').append('<a href="' + large + '" style="background-image:url('' + thumb + '')"'+classes+'>');

Hope it helps.
