Hi,
In your options, you have a thumbnails size of 100*300. So the system resize the thumbnails to fit in that box. And then there is now some additional CSS in order to handle the badges which fixes the width of the thumbnail area based on your settings.
If your thumbnails are all around 100*100, then you should set the thumbnails size to 100*100 and not 100*300.
That's why the images are shifted to the right as they are centered on 300px.
So you can fix that by setting up properly the size of the thumbnails.
But if you want a fast solution, you can just add that CSS:
.hikashop_product_image_subdiv{ width: auto !important; }
but note that the badges won't be aligned properly with that solution if you plan to use them in the future.
