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.

vipscaler might be a solution

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

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.
