Hi Ernest I found a work around. I deleted all the tags that repeat what the title said and hey presto the results for products with the images come first.
Would be a nice addition if you added more customisation for the woocommerce results ie price in a didifferent colour with an option to add directly to cart or to wishlist. Then this plugin would be a force to be reckoned with in the woocommerce arena.
Thanks for the help.
Took me all day to delete all the irrelevant tags but my site is better off for it. It gives nice results.
