Virtuemart 1.1.9 - Automatic Image Resizing product

[robertosalemi]

Hello users,
there is a hack or a guide that allows the automatic resizing of the image of the product (not the thumbnail) with the predetermined dimensions, just as they do for the thumb?

I wish rimensionamento happen during upload so that it is displayed correctly in both frontend backend.

To the limit in backend would suit me even a reduction by CSS.

Thank you.
