I have created a Flikr group so that people can share their photos if they wish. I went for Flikr as it allows the photos to be downloaded at the maximum resolution and doesn't change them like Facebook does.
You will need to set up a Flikr account if you don't have one to contribute but its free. Upload the pictures to your account and then add them to the group. I have put all of our photos in there. The URL is https://www.flickr.com/groups/ionianflotilla2017/
