No, but it's basically telling you the right way to do this is to resize the image to the same height/width in a graphics program (don't rely on the browser to do this for you). The browser may not do as nice of a job resizing as a graphics app and you're making the user download more info than is needed. BTW - the size is supposed to be an integer, ex. the ,5 a is meaningless pixel size.
