Photo Sharing corrupts perfectly good images.

How do I file a bug report? I don't see any mechanism... typical. Worse support than Flickr or Google.

To file a bug report use the feedback form: Apple - Photos - Feedback

I have the same issue ... It has done this to nearly a hundred of my photos..

Same issue here for the 1st time - running Photo Version 1.3 (350.23.0) on El Capitan 10.11.2 (15C50).

I have tried and republished several times as well as restarted Photo - no success.

Very disappointing, all the more during this festive season.

Same here. It's very reliable. In truncating images when posted to sharing. My photos are fine. I suspect they just upload and if one post fails they keep the broken copy, instead of checking and re-transmitting. Very poor, same as Apple Photos' instability in general. Time to think different, sigh.

Holy snipping magic ... it's getting worse. I just exported a few photos locally to JPEG and got truncation even there. Worse: the images are not damaged, they just contain white = undetectable by image viewers. This is terrible. Need to drop Apple & Photos, can't risk any more data destruction like this ...

Repairing my library fixed the issue for me.

Rebuilding did not help. Still happening. The original images (RAW from a Nikon D610) are fine. Sometimes the export works. Also running the latest OSX (10.11.3).

The cause of this I've somewhat identified: if I start an export and don't touch anything in Photos until it's done there won't be anything broken. Clicking around, viewing images in the album and some shared ones and I end up with damage.

Have you reported this buggy behaviour to Apple? That is looking like a serious problem.

The export is done by a process running in the back ground. Clicking around should noti nterfere with this process in any way-

Just reported it. Let's see what will happen. In the meanwhile: don't touch anything while exporting 🙂

Another observation: I just had 700+ 24mp RAW images imported. Apple Photos started processing them in the background, which can take a long time (preview, face reco, etc). During that period every export of 11 files (not part of the import) failed, i.e. truncated images. Export to local and photo sharing that is. I removed the RAW files (processing was still going on) - exporting back to normal.
