using the script/command pngsize

This little program finds the width and height (in pixels) of one or more PNG files, and displays the information in a form which can be pasted into a web page. For example:

newton>  pngsize *.png

<img width=40 height=40 src="greenball.png">
<img width=204 height=206 src="rooster.png">
<img width=18 height=18 src="section.png">
<img width=122 height=158 src="splash.png">
<img width=46 height=44 src="zap.png">
