I'm having trouble changing the size of the product thumbnails. I'd like them to all be as large as the thumbnails for the featured products. I've tried going into virtuemart>configuration.configuration and changing the thumbnail size but it doesn't do anything.

From webroot I've tried going to /templates/ot_ante/html/com_virtuemart/category/default.php but I'm not sure what I'm actually supposed to edit there.

Thanks!

After config thumbnail size you should upload new images for product.
