Maybe yours are, but none of mine are.  All my pages will look fine 
anywhere from 300 wide to 2800 wide.

Rastor-based Images as we know them on the web- gif/jpg/png, cannot be 
dynamical sized based on anything without failing to pixelization of the 
image.

Only Vector-based graphics can be scaled.  I for one refuse to place 
Flash/swf on my webpages, and thus, will not have an option to show 
vector graphics to my users.

Marked, maybe- but it won't work with desirable results.

Now you're on to the same thinking I am :)

So, if a windows meta file is added, as you sugegst above, rastor images 
can now be scaled without pixelization?

Even if it does work-  What about Linix, Unix, Mac/Apple, and BSD 
operating systems?  They don't have windows meta files.

Good ideas- i just don't see it ever being feasable.
