logically, find this:
PHP Code:
if ($width > $vboptions['attachthumbssize'] OR $height > $vboptions['attachthumbssize'])
and put this just before:
PHP Code:
if ($width < $vboptions['attachthumbssize'])
{
$vboptions['attachthumbssize'] = '100';
}
so if the files are bigger, the new default for thumbnails will be lowered to your prefered size before the treatment...
...and you can count you as a lucky guy, i never give codes for free usually.. i suppose it's the time of night...
