validation -> upload -> min width/height

[nrm]

upload method have

// Maximum image size, eg: 200x100
list($maxsize['width'], $maxsize['height']) = explode('x', $param);

and what about minimum image size, if we don't want small photos? i have some gallery sites and i know that users often upload too small pictures (ex. thumbnails, from cellphones etc.) when we need more then ex. 800x600. It would be very helpfull option to set minimum and maximum size of uploaded picture.
