Medium sized images missing

[Aceicol]

Hi

 

I have installed a contribution that allows me to have 3 sized images on my site (small, medium and large). I can see all the small images by going to the product list page (so I know they are all there) however I want to know if there are any of the Medium and large images missing or wrong address. I can't go through them all as I have over 8000+ products and it would take me forever.

 

Thanks

Alex
