No Manufactures Logos in Manufacturer Block

Hi,
When clicking into manufactures block, logos are not displayed. Instead “Not Image Availabe is displayed”
You can see the issie here: http://atempo24.com/en/manufacturers
Standard Prestashop Theme display them correctly
Browser: Firefox 19.2.2
Prestashop: 1.5.3.1
Thanks for a quick fix
