Thumbnails aren't displaying after adding a product

[hidmedia]

Hi All,

 

I am quite new to prestashop though I have been building sites for a few years now. I am converting the Leo Converse Free theme from Leo Themes and I am stumbled into a bit of an issue.

 

When adding new products I am finding that it isn't generating a thumbnail for the product when you click on it.

 

I have added a link below

Any help would be amazing as I really am stuck!

 

Thanks in advance,

 

Marc
