Hi, I'm having this same issue and I tried this fix from Nicolas which worked, but when I use products that have more than one thumbnail I lose the larger image when you roll over the thumbnail. How do I fix this issue? You can see an example
here.

Change the line:
$this->uploadFolder_url = JURI::base().$this->uploadFolder_url;
to:
$this->uploadFolder_url = JURI::base(true).$this->uploadFolder_url;
in the file administrator/components/com_hikashop/helpers/image.php and that should circumvent the problem.
