[PHP] file_exists on different server...

[Tristan . Pretty]

I'm referencing an image on a different server, and it keeps changing 
URL's
Very odd, but t get round that, I tried...

if (file_exists("http://www.othersite.com/image_1.gif";)) {
        $image_show="http://www.othersite.com/image_1.gif";;
} else {
        $image_show="http://www.mysite.com/image_1.gif";;
}

but it always seems to do the else command, even though I know the file 
DOES exist...

Just for the record, this problem exists from our parent website to one of 
the subsideries, we're not referencing anything we shouldn't... ;-)

Any work arounds?
