I am looking to move away from SmugMug as I really do not use it as intended. I got it as a black Friday deal and do not want to renew. I have a flickr account and really do not manage it as I feel like it is nothing but sponsored post and a black hole. I have looked at 500px but do not know if it is the same? I use Instagram but the whole only upload images through your phone. (yes I use the LR app but can not multi-photo post) I like SmugMug as I can send links to friends on gallery but at the same time, I do not use a custom URL so I think people avoid clicking the link. What options are best for original files, some kind of protection, and user fed back?
