i hope this is the right way to ask about this detail:
I have some privacy concerns.
Assume i accidentially selected the wrong file in the file-select-dialog of my browser while creating a toot.
The media/image is immediately uploaded to the instance.
What happens with this image if i choose to delete it and select another image (or decide to not post any image after all)?
Is that image that was uploaded in the first place properly deleted?
Is it cached somehow and deleted by cronjob like house-keeping task?
