note ybiC I like it, thanks [chromatic].   May I throw a slight curve in the fairway? A quick dig in [isbn://1565922573|The Owl] leads me to think something like this will match reference any image of alphanumeric name.   How close am I? <code>perl -i.bak -pe 's!(img src=")(\w+?\.(gif|jpg|jpeg|png)")!$1/Images/$2!g' *.html</code> Update: The above one-liner was tweaked, and now works.     Changes this: <code><img src="12345.gif"> <img src="1b3e5.jpg"> <img src="1B3Df.jpeg"> <img src="abcde.png"></code>     To this: <code><img src="/Images/12345.gif"> <img src="/Images/1b3e5.jpg"> <img src="/Images/1B3D5.jpeg"> <img src="/Images/abcde.png"></code> And saves original files as ".bak".     cheers,     Don     striving for <a href="http://prometheus.frii.com/~gnat/yapc/2000-stages/">Perl Adept</a>     (it's pronounced "why-bick") 43168 43175
