Content type header doesn’t seem to be being sent for images:

Is this something you all can fix?

Well, let’s try
Freshly uploaded image
And the result of curl
$ curl -I "https://d11a6trkgmumsb.cloudfront.net/original/3X/a/a/aa245d9f64088f61ff802a099020cc16bdc2e893.png"

We can’t repro this, can you provide more info on how to repro?

It affects the url https://discourse-user-assets.s3.amazonaws.com/ which is on Amazon S3 not fastly. The content-type header isn’t set for images which can cause issues for certain http clients and even old web browsers.
ok @supermathie can you have a look?

It isn’t exactly the same test, correct, but accessing our storage bucket directly gives us:
○ → curl -I https://our-image-bucket.s3.amazonaws.com/original/3X/a/a/aa245d9f64088f61ff802a099020cc16bdc2e893.png

Correct Content-Type header. But again, not exactly the same test (png vs jpg).
Uploading your image to our bucket (via the normal file upload interface) gives:
○ → curl -I https://our-image-bucket.s3.amazonaws.com/original/3X/f/f/ff5fe6693f4d56b6b6b768d91f10bd4cdd9f3eb2.jpg

So it’s behaving correctly for us. Given that the upload date of your file seems to be roughly a year and a half ago it’s possible this used to be a problem but has now been fixed. Do newly uploaded images show the same behaviour?

I can confirm that new image uploads are not affected by this bug. By any chance are you guys are to iterate over all of the old images and assign a mime type where one is not already specified? Very minor issue, still a concern.
