Set a different product image format on certain categories [PS.1.6]

[Attrexx]

Hey all,

I keep struggling at finding a way to achieve something that, as far as I know, Prestashop can't do by itself, and that is setting a different format (let's say a VERTICAL one) for a certain category, as opposed to the rest of the categories where I could use the default format, ie. SQUARED.

Do you have any ideas on how one could get something like this in Prestashop PS1.6?

I need it for a store that sells shoes (squared pics) but now wants to add a special category with clothing (vertical pics) and resizing/fitting/cropping the clothing images to fit in the square format has a major negative impact on user experience and product showcasing.

Any idea is welcomed! Thanks a bunch.
