Working out the image path...

Hey! Am having a little problem working out the logic in this, basically I pass a graphics path to a function and it should give/retrun me the URL path. <?php $url='http://x.com/t1/t2/t3/blah.html'; function ret_url($rel_path) { } ?> so I pass a relitive url like this $a=ret_url('/blah.jpg';) and (using the above sample url) it should return me: http:// www.x.com/blah.jpg, which seems easy enough except that there are some other combinations... So far these are the combinations I could think of that will be used...correct me if I am wrong by adding or subtracting: /blah.jpg // should return http://x.com/blah.jpg /imgs/blah.jpg // return http://x.com/imgs/ blah.jpg imgs/blah.jpg //return http://x.com/t1/t2/t3/imgs/blah.jpg ../imgs/blah.jpg // etc /../imgs/blah.jpg //etc http://some-site-blah.com/imgs/blah.jpg // return the same url To try and do the above I was fooling around with parse_url() and explode() but cant work out the logic, if it helps, heres what i did so far in my "experiments" $parsed_url = parse_url($url); $thissite = $parsed_url['host']; $thispath = $parsed_url['path']; echo "$thissite <br> $thispath<br>"; $pieces= explode("/",$thispath); print_r($pieces); ANY help appreciated.
