I am retired but would like to show my images in Getty Images. I have tried to send an email to them registering and giving a URL to my set of ten images on Flickr for appraisal as they ask for. Unfortunately the email keeps bouncing saying unable to deliver. I have tried to register but some questions are related to businesses so the questions are not relevant to me as I am retired. Is all this possible or do I have to wait for a invite from them via Flickr? Is it possible to upload images to Getty without an invitation?
