I use
https://imgvek.com photo and image hosting and it has a good drag and drop feature where you can drag and drop a whole folder of pictures and upload them with ease.
Also before I started also using
https://imgvek.com image and photo hosting I have used and still use
https://photobucket.com
Google Drive is also good for storing photos and protecting them.
https://imgvek.com also has an option of keeping your photos private if you want to just share your photos with family and friends.
Or if you just want to store the photos and access them yourself then you can set your
https://imgvek.com photo album to private.
They have paid and free accounts although I currently use the free account which is enough for me.
