How to find the HxW of thumbnailHxW

I've setup an integration between HikaShop and a Joomla content construction kit. The CCK queries the HikaShop tables to get various information including the image name. In previous versions of HS, all thumbnails were in the same thumbnail folder making this approach quite simple. With the newer version though, the thumbnails are in a folder named with the dimensions.

Is the dimension information stored in the database somewhere that I can query for it to fix my integration?
If not, is there a way to create all thumbnails in a single thumbnail folder instead?
Possibly using a plugin? I'm reaching for ways to make this work again.

Here's the query I use to draw HS info into the CCK.

SQL Query:
	SELECT
	  concat_ws('|',
	    convert(product_id,char),
	    file_path,
	    product_name,
	    db_menu.id
	  ),
	  product_name
	FROM db_hikashop_file
	JOIN db_hikashop_product ON product_id=file_ref_id
	JOIN db_menu on published = published
	WHERE file_type='product'
	  AND db_menu.link='index.php?option=com_hikashop&view=product&layout=listing'
	  AND db_menu.parent_id=1

	GROUP BY product_name
	ORDER BY product_name,file_id desc

I'd considered parsing the folders to find the image but was hoping for a better way. I like the idea of having HS show the image but how would I go about that in a separate php file?

That worked perfectly and was a far better way than parsing for thumbnails that might not exist yet. Thank you!
