See my edit above outlining that the HTTP protocol specifier's '/' needs to be between the HTTP and version number.

I just reviewed the philips http module and it has this:

requestText += " HTTP/1.0\r\n";


write("GET /t/p/original/"+cover+".jpg HTTP/1.0\r\n");
write("HOST: image.tmdb.org\r\n");
write("CONNECTION: close\r\n");
write("\r\n");
