Yea would like to know how you did it aswell
figured out a solution by editing the image output in href rather than removing the href alltogether
Looking over the source from FF, I see the get_the_post_thumbnail argument creates an IMG SCR output automatically, question then is, where do I edit the output of this?
I have btw also tried it with the following without any luck
if ( $image_size && has_post_thumbnail() ) $image = '<img class="contentrotator-thumb" src="'. get_the_post_thumbnail($post->ID, $image_size).'">''</img> ';
