If one clicks on a matrix.to link, the image doesnt load, see for example my profile.
I'm using firefox, which says "NS_BINDING_ABORTED" (but curl is also unhappy as it returns {"errcode":"M_INVALID_PARAM","error":"Query parameter width must be an integer"}).

Interesting, given that this is trying to request the image via a Synapse server - https://matrix-client.matrix.org/_matrix/media/r0/thumbnail/pngn.cc/FYQCHT95bsd9zN9ce2UJTXlACrNnNp8S?width=64&height=64&method=crop is giving:

May be to do with unauthenticated media being disabled - if you tell matrix.to to go via a continuwuity server, you get a 403

matrix.to's media doesn't work after authenticated media was introduced, https://github.com/matrix-org/matrix.to/issues/351

That error sounds... erroneous though, more like a malformed request than anything.

Regardless, I visited the matrix.to link you sent and changed my preview server to one with unauthenticated media enabled, and it loaded fine: https://matrix.transgender.ing/_matrix/media/r0/thumbnail/pngn.cc/FYQCHT95bsd9zN9ce2UJTXlACrNnNp8S?width=64&height=64&method=crop.
