Generated pictures are not shown in module

[name368]

Hello,

 

I cant solve this problem for a long time. I will be grateful for any help.

 

picture 1 - On my website ( http://kovania.eu/prestashop/ ), i have module "previously shown products" (Zobrazené výrobky)... This module does not show +-20% of uploaded pictures.

 

Strange is that i can fix it temporarily:

1. temp fix - i will delete all pictures and upload only 1 - picture will be displayed... If i upload more images - 2+, it will not work again.

 

2. temp fix - if i have 10 images uploaded at one product, i will choose one main picture, then i delete him - new picture will be automatically selected and then it will appear again at module. If i choose a new main, it won´t work again.

 

Im uploading all images in jpg format, and regeneration of pictures does not work (probably timed out).

 

Could someone help me please?
