No Images For manufacturer/all

Hi, 

In the header (using Mega Menu) I opted for the Manufacturers to be shown as a dropdown. But the manufacturer/all is showing no images for the manufacturers. Any idea why and how I can fix this. I uploaded an image for each manufacturer but they do not show on the manufacturer/all page.

Hi,

Can you go to one of the missing images, inspect it and see if the link is valid ? 

It will be best to provide as with a link to your website.
