Comment (by azaozz):

 Replying to [comment:14 ironprogrammer]:
 > it would help to at least add support for `image/heif`, as originally
 reported for this ticket, since that seems to be a common mime for sample
 spec images. A `.heic` file returning `image/heif` should be considered
 valid.

 Right, my thinking too. The other two mime types can be "partially
 supported" for now, i.e. don't prevent uploading, but the results of
 converting them to JPEGs may vary.

 > I don't think original uploads should be renamed to match the mime. The
 HEIC designation hints that the file has a HEVC encoded image (like
 attachment:sample1.heic), which is valid as `image/heif`.

 Yep, this seems most compatible. Went with 1 above: all HEIC images have
 .heic file extension.

 > found that ImageMagick (`magick` CLI) grabs the first frame when
 converting to JPEG, so seems to work okay at a glance. However, for lack
 of finding a real-world use case for this, I think supporting sequences
 should wait until there's a defined need.

 This is somewhat similar to the support for animated GIFs: when resized
 the sub-sizes are of the first frame only. Also thinking this can be left
 as-is for now and revisited if the need arises as these images seem
 extremely rare for now.
