Hi i recently installed SIG and no matter what i do i keep getting the same error

Warning: opendir(/home/global/public_html/tyrebelts.co.uk/images/stories//images/gallery/beltslideshow.jpg) [function.opendir]: failed to open dir: No such file or directory in /home/global/public_html/tyrebelts.co.uk/mambots/content/plugin_jw_sig.php on line 46

I know the files exist and that the link to them is correct but i cant get it to work.

You can see the error here: tyrebelts.co.uk/index.php?option=com_content&task=view&id=12&Itemid=28

Untill this i was considering paying for the pro version but i cant see that happening when this version fails strait out of the box.
Any help would appreciated.

Thanks
Gila
