Right-o. We've batch converted the images to JPG and are very happy with the resulting quality so will likely post those instead of the TIFFs because we want to make absolutely certain they work with the media player and can be scaled and downloaded at different resolutions. In fact on reflection, the TIFFs were so huge that we're not even sure they would be that usable for the average person, they crash the simple image viewers on our own PC's, and if the only option to view them in the commons is by download (ie they aren't able to be scaled and downloaded at different res in the viewer) they won't be much use to the greatest number of folks. We also would love for them to populate articles if possible so I think JPG is the most practical way to go for this batch. Though I certainly take Fae's point from last year around not shying away from a challenge and opportunity to fix something, I'm sure there will be more opportunities for that with future BL batches!
Thanks everyone for the feedback/convo!

large tiffs are not rendering in commons. "The bug is in the MediaWiki thumbnail generator," https://commons.wikimedia.org/wiki/Commons:Help_desk/Archive/2015/02#Polar_b...

Re Fae's comment: I'm not sure what you mean. Tiffs work fine in media viewer for me.
By this, I mean that you can't view the fullsize TIFF within the viewer or browser, while other formats work as you might expect.

Oddly enough, vips scalar was the problem here. There used to be a bug that causes that, its been fixed now (for a long time now), but the old version was cached. If you see any images that are almost entirely white with a bit of black around the edges, do ?action=purge to the image description page.
However there appears to be a second bug ( https://phabricator.wikimedia.org/T116947 ). Rendering the file in sizes less then 2523px seems to be broken.

thanks - non-render size up to 50 MP which should get most images in use
but there are still some larger " Error creating thumbnail: Invalid thumbnail parameters or TIFF file with more than 50 MP "

There shouldn't be (anymore). Do you have any examples of files with that error?
There are a few (I mean few as in probably less than 10 over all of commons) tiff files that don't render that I am aware of, but they don't have that error and instead just time out.

If possible, could you upload both. Its nice to have the original too, even if not used in articles, in case some later person has need for it.
if the only option to view them in the commons is by download (ie they aren't able to be scaled and downloaded at different res in the viewer) they won't be much use to the greatest number of folks. We also would love for them to populate articles if possible so I think JPG is the most practical way to go for this batch.
To be clear, this is incorrect.
Fae was complaining that for tiff files, if you click, "view original image" (or the mislabeled equivalent "zoom" in the media viewer). You get the original full sized tiff. Which kind of sucks (For reference, the same thing happens with large jpegs). However, tiff files (of any size) can be scaled to jpg or png of reasonable size (We don't support scaling a 200 megapixel tiff -> 200 megapixel jpg. But we do support scaling of big tiffs to any sort of thumbnail size you'd find in an article). There is a bug with 16bit tiff files, but all other tiff files should render fine.
Anyways, before making a decision, I recommend you judge for yourself. Here's what the tiff file you uploaded to beta would look like in an article: https://test.wikipedia.org/wiki/User:Bawolff/example_tiff
