atomatic fitting of the images

Hello I use this module to show mi client's logos. Now you can imagine that each client has a different logo in terms of size, is there a way that the module fits automatically the image to the parameters I set up so that all logos are similar??

thank you!!!!!!!!!!!

it will be stretched if not same aspect ratio W/H, best if you put all logos graphic on some transparent surface in .png images so all images would be actually same size.

ok, thank you Ivan
