Create a different image type size constraint

[lulucious]

Hi everyone,

 

I am looking to adapt the image types offered by prestashop.

 

Now, prestashop requires both the MAX WIDTH field and the MAX HEIGHT field.

 

I would like to simply put a constraint on the width or the height and to set it to a given value in px. Afterwards, i want the other side to be be resized accordingly.

 

Any advice on the PHP changes I should consider doing?
