Looking for an file hosting service with some specific features

Hi, I currently use Zipline to host my files for easy retrieval across systems and sharing. It generally works well, but is lacking in a few places that cause some friction. I mostly store and share photos, though I want it to support arbitrary files.

I usually upload a batch of several very similar photos since I take many whenever I photograph something. I want to be able to group these sets into a single object so I can collapse them when browsing my stored photos.

I want to be able to manage(delete, download, add tags) several files at once. As far as I can tell, zipline does not allow this.

I'd like to have tags that can implicate other tags, or at least have a sub-tag system. For instance, the last photo I added was of a Great-Horned Owl. I'd like to be able to add a 'Great-Horned Owl' tag, and have it add 'Owl', which adds 'Bird', which adds 'Animal'. I don't particularly want a hierarchical folder structure, as I'd still like to be able to view any combination of the tags, or all photos at once.

From Zipline, i'd like a basic visual dashboard with authentication and API upload access. I would ideally like filename randomization, metadata stripping, and non-administrator users, but those aren't required.

I care about ease of use more than visual appeal.

Let me know if this isn't enough information for a suggestion and i'll happily answer questions/edit the post.

Thank you.
