Cannot upload logo

[XeR]

Uploading logo when creating (not importing) a CTF converts it to data://.
The resulting URL is too big for the database.

We either need to write an upload script or upload the logos to the Internet.

Maybe we can use MinIO ?
This appears to be a clone of Amazon S3.
This is one of the 3 self-hosted ways to upload images to Hedgedoc.
On top of that there is a neat guide on how to set it up.

This feels a bit overkill for something as simple as uploading a logo.
Might be worth looking into if we wish to expand CTFNote with file upload capabilities for stuff such as exploits, challenges, etc. (but do we ? Is this really a feature in the scope of CTFNote ?)

I think it would be amazing to also have a small file share per challenge! It would completely eliminate the need of external communication channels during a physical CTF
