Since it doesn't sound like you want to share these to the general public, but specific people, I'd recommend something like Microsoft Onedrive, Google Drive, or Drop Box.
You upload your files, and you can share them with specific people, allowing only those you share with access.
Flickr provides the ability to keep albums or pictures private, only allowing access to those you have provided a link to... I would guess many other sites do as well... but you are correct, a site like Dropbox would work, but might not allow them to easily see the images before downloading.
