nah...that would mean:
ghijpgklmno
or
mnopngqrst
or any text having those letters within it would be captured. however,
neither his nor yours work unless the string ends at the end of the line
(eof or \r or \n). both don't escape the dot...so that means 'any character
followed by jpg or png'. more marginal success would be had just doing,
"/\.jpg|\.png/", but even that doesn't cut it...since either jpg or png can
be followed by anything and still be captured. not to mention we've left out
jpeg's.
make sense?
