Same here, I'm glad to read that I'm not the only one who couldn't make it work!
But it seems that nobody else worries about not using the method Getty is providing for posting their (unlicensed) images on websites, blogs, message boards and other social media?
Arthur used the direct link to the Getty image in his posts further down, which is probably better and easier than to upload the image to a host like Photobucket or Postimage. The embedding code provided by Getty however is supposed to add all credits that the company considers to be necessary in order not to violate their copyrights and by copying the code the user agrees to their terms of use.
Now I don't think that Getty and their lawyers are watching this board, but the fact that they provide a method for the use of unlicensed photos on the internet is quite accommodating and I'd somehow prefer to stick to their rules.
