Moving to signoff for visibility, as this is expected to be marked down as "declined" rather than actively being worked on!
^ CC @cmadeo in @JScherer-WMF's absence
50px LGTM! There's a patch up for review, but will wait for @JScherer-WMF we're good with 50px before merging!

can we make the decision on source image vs thumbnail size?

Closing - we have T429512: [Image Browsing] Determine image size requirements for carousel to investigate further adjustments.

Updated the task description because the transparent images in the viewer are not related to dark mode, instead the media viewer has a consistent dark background in any mode.
Dark mode does pose a problem for transparent images in the carousel. Do we want to apply the same checkered background to transparent images in the carousel?
light mode dark mode Demo with a checkered background:
@JScherer-WMF I'm beginning to think 100px might've been a tad bit too aggressive. E.g. we're losing all of these gallery images https://en.wikipedia.org/wiki/Mount_Kenya#Peaks; none have a height of 100px; the first 2 images in https://en.wikipedia.beta.wmcloud.org/wiki/Vietnam_War also don't make the cut.
Maybe we should consider decreasing the limit somewhat?

| enwiki beta | ... |
|---|---|
https://en.wikipedia.beta.wmcloud.org/wiki/Vietnam_War - two first imgs from the info box are not present in the carousel  | Those image are missing intentionally, because they're < 100px in height (T428810) |
https://en.wikipedia.beta.wmcloud.org/wiki/Cactus_wren on enwiki beta the image from the infobox (File:Status_iucn3.1_LC.svg) is not present in the carousel - otherwise, all imgs are displayed as expected  | That image is missing intentionally (T428597) |
Yes, seems like the same issue as T428610 indeed, so should also be fixed once that lands!
@KSarabia-WMF already took care of this in https://gerrit.wikimedia.org/r/c/mediawiki/extensions/MultimediaViewer/+/1290769, which should hit production this week.

The carousel is a more limited set of images than <all images in the article>; the size limit is a big differentiator, but there are also a bunch of files excluded for other reasons (e.g. signatures)
IMO, the carousel is not a separate set of imagery (where clicking an image opens a lightbox with only those), but rather just another entrypoint into MMV (which may include more media than exclusively carousel) - much in the same way that clicking an image in a gallery launches full MMV rather than a lightbox of just those images in the carousel.
IMO, the current behavior is the intended/desired one.
