Wrong image path for products and categories

[ceciler]

Hi all,

 

I just installed Prestashop 1.6 on my computer using MAMP. Adding pictures to the theme (logo, slider, etc.) is not problem but when I add pictures to categories and products I get an ugly question mark picture.

 

It seems the URL path is wrong - indeed, when uploading a product picture (or category picture), it automatically goes to root/img/p/2/5/25-home_default.jpg (+ a bunch of other thumbnails).

 

But when I go on the site the URL of the picture is: root/25-home_default/filename.jpg

 

I'm not sure how to fix the path. Does anyone know how to do it? Thanks!
