Will epub devices automatically scale large images down

As I mentioned before the implementation of ePub 3 (HTML5) will be based on the pixel size being scaled properly when compared to a computer screen with 96 px/i

It should not be too difficult to implement image size reducing so it fits if it's being displayed off screen. I'm surprised it wasn't implemented.

I have seem many ePub with the cover not fitting properly on screen.

Does it help if an image is inserted with no size specification at all (or only max/min sizes)?

<div>
<img src="200_px_wide_image.png" alt=""/>
</div>

If displayed at the native resolution, the image may be readable in a low-res screen, but too small for a high-res one.

This may be "fixed" in the code by specifying "width:200px" for the image, but I really think the default resolution for images (in the sense it affects the above sample) should be adjustable.

I think it depends on OS differences, browsers.
