The build seems to be choking on the thumbnail image. I'm not immediately sure why.

Reference: this build log which is producing

⛔️ 940b2fbbda490bffbf834be770b29aa6 Error saving image "https://raw.githubusercontent.com/projectpythia/snow-observations-cookbook/main/thumbnail.png": https://raw.githubusercontent.com/projectpythia/snow-observations-cookbook/main/thumbnail.png content-type "text/plain; charset=utf-8" is not an image
⛔️ root.md Unsupported image extension "<no extension>" may not correctly render.

The build seems to be looking for the thumbnail image at https://raw.githubusercontent.com/projectpythia/snow-observations-cookbook/main/thumbnail.png instead of https://raw.githubusercontent.com/projectpythia/snow-observations-cookbook/main/thumbnails/thumbnail.png. The path is wrong. Will see if there's an obvious reason.

[brian-rose]

@aaarendt the build failure is because the thumbnail image is in a subdirectory thumbnails in your source repo, but this is inconsistent with what is specified in your _gallery_info.yml.

The reason for this inconsistency seems to originate in our Cookbook Template, so this needs to be fixed upstream.

But the solution here is to do either:

1. Move your thumbnail.png to the root of the source repo, or
2. Edit this line of your _gallery_info.yml to have

thumbnail: thumbnails/thumbnail.png

Either one should work fine, and it's just a matter of taste for how you keep your repo organized.

Thanks @brian-rose, I moved the thumbnail to the root directory as suggested.

Gallery build is passing now. I will make some suggestions over at https://github.com/ProjectPythia/snow-observations-cookbook to resolve some current build issues for the cookbook.

Thanks @brian-rose. Is this to do with the nightly builds failing? I've tried to fix but couldn't figure it out. Let me know if I can assist.

On closer inspection, the nightly builds are passing, it's just that the badge on the README page is still pointing to the Cookbook Template (which is currently broken). I will open a PR to fix that.

@brian-rose I think this is ready to merge?
