The second one is to get the web server decide which image file is
better.  An Apache httpd module can select the best response for a
request for image "the-company-logo" if it knows which size is needed,
and what mime-types are acceptable.

My idea is to add a field to the http request header for image files,
to let the server know which size the image is going to be shown, and
then it decides to send the best answer.

What's wrong with URL parameters?

<img src="logo.jpg?width=100px&height=100px" width="100" height="100">

Your server-side code could see this URL and serve an appropriate image.
