Add file type validation by using header inspection, only accept images

bartjkdp opened this issue · 2 comments

As a follow-up of Amsterdam#769 we would like to add file type validation by using header inspection.

Suggestion of @ericherman:

This corresponds to ticket SIG-3667 that is in the current Amsterdam development sprint - I will update this ticket with a reference to a PR once we have one.

Proposed implementation currently under review: Amsterdam#790
