Crop images when uploading prestashop 1.7.7

[Agustin Sysprovider]

I have the problem that when uploading for example this image that belonged to a prestashop 1.6 store https://www.jolumara.com/img/p/2/0/2/0/2020.jpg in prestahop 1.7 the image is cropped and the image looks like this :
http://jolumara.cmsfacil.eu/inicio/2302-prueba.html . 

Both in the product image and in the thumbnail, why does this happen, I must configure in prestashop 1.7 to respect the images of prestashop 1.6?
