$imgdata = file_get_contents("http://somedomain.com/someimage.jpg");

but this assumes that your php setup has the allow_url_fopen ini setting
set to true/1, see here for more info:
http://nl2.php.net/manual/en/ref.filesystem.php#ini.allow-url-fopen

if not then the only other way _I_ can think of, using PHP, is using the
cURL extension - which maynot be available either :-S

regexps is the way to go, I did a quick google and found this post:
http://forums.devshed.com/t173149/s.html&highlight=parse+image

there is a little code snippet there which might be a starting point for
you.

here is an untested regexp which goes a little further, it assumes that
the img tags have the src attr properly delimited and specifically
delimited with doublequotes.

|<img [^>]*src="([^"]*)"[^>]*>|i

hope that helps you on your way.

(hey list-guys! look no rtfm'ing in sight!)
