The imghdr module is being deprected in 3.11 and will be removed in 3.13. See PEP 594 for details.

We currently use it only in one area:

Alternatives would be:

1. Just use the mimetype module? We were using only the mimetype module until @b83a659 where we used a 'hack' to detect the type from the byte stream. This was then replaced by the imghdr module which did the same thing better.
2. Use a library called filetype to detect images. This was recommended by the PEP.
3. Just copy the python source of the imghdr module into ours?
