Lightroom 6.10: Export from DNG to JPG for Flickr results in "not an image file"

Lightroom CC2015.12/6.12 was released today and should address this issue.  Please update your Lightroom to the latest version and let us know if you continue to see the issue. Thank you for your patience.

Are you using a direct upload?
A plugin to publish direct?
Lightroom's built-in Flickr Publish Service?

I don't think that this is a Lightroom problem but a Flickr one. I use Jeffrey Friedl's jf Flickr plugin to do my uploading and it just displayed the following error.



This must be something Jeffrey has seen often enough to warrant adding a specific error message for it. I got the error twice in fairly short succession, then checked if there was an update for the plugin. After downloading and installing the update and reloading the plugin, the third attempt got the image uploaded successfully.

I think you just need to keep trying to upload your images.

Definitely not a new problem. Just found this old closed Flickr forum thread from 2014 discussing it.

@Rikk: I am using direct upload, no plug-in. Just a flat export from an edited DNG file, to a JPG, into Flickr upload. Has worked flawlessly. Btw - I am on a Mac OSX platform (no clue if relevant), 10.12.4.

@Steve: thanks for the link. Appears that I should either just "remove" the LR exported file(s) Flickr does not accept, and/or keep retrying. Not great, but worth a shot. Thanks a million for your help.

@Carl

Are you still having issues today?

Hi Rikk - I do not know what you did...but it works flawlessly for me now. Tried two different ways (both direct and via plug-in), both failed yesterday, both work now. Many thanks!

Probably what "Flickr" did - not me.

Flakr has been notoriously unreliable for the past several years, after they redesigned the service and Yahoo entered its death spiral.
