Any cloud service. I personally use Google Drive for large albums and just a WeTransfer if I have to quickly share some shots.
Photography
A place to politely discuss the tools, technique and culture of photography.
This is not a good place to simply share cool photos/videos or promote your own work and projects, but rather a place to discuss photography as an art and post things that would be of interest to other photographers.
I use several drive services like Google Drive, One Drive, and even Dropbox if needed.
Now, I do share the folders to whoever has the link, they are not exactly public, but depending on the context and client / final user, they can share among themselves. Imagine a wedding where I send the photos to the bride and groom. They are free to share that link with the guests if they want. I have the photos for sale in my website anyway (print sales, not digital downloads or whatever).
This is more than enough and everyone can open and download the photos with quality and not worrying about spamming or sharing your email.
Pic-time has a free option, a great interface, and implementation for photo sales and prints. Dump all the pictures in there and send one link out to everyone.
