[ale] Excuse me for my web stupidity. Working on displaying output to a browser.

The best way to insert line breaks is probably add <br> instead of CR/NL. That way you get a
broswer independent way of formatting your images..
I would change the code to :

if(c==10)
	printf("<BR>");
else
	putchar(c);

Hope it works..
