Encrypted chat pictures get blossom.yakihonne.com as a third host; a small file stops at two copies.

Benchmarked 18 public Blossom hosts: only ditto, nostr.download and
yakihonne take opaque (application/octet-stream) blobs, which is what an
encrypted attachment is. ditto is fastest; yakihonne is slow, so it is
reached only when one of the first two fails.
