Flickr appears to have redesigned the way you view images.  It was easy to download images before but I had a very hard time trying to figure out how to download an image.  If I right click on an image and hit “Save As”, it won’t work and just saves an html web page.  I finally found out that you have to click the 3 white dots on the right side of the screen to get the option to save the image.  I wonder if they purposely made it hard to save an image.  You can finally easily download all sizes.  Below is a screenshot.   flickr how to download images
