How to limit the weight of product images

Good Morning

I do not know if this query corresponds to Hikashop or Hikamarket.

Is there a way to limit the weight (KB) of an image when loaded from the frontend?
It happens to me that when a vendor (hikamarket) publishes or edits products from the frontend and loads a very heavy image, more than 2 MB, the image is loaded rotated, if it is originally vertical, it is loaded horizontally.
There is also the problem of server space and page load speed.

Thanks greetings !
