* Add og:image:width, og:image:height, and og:image:type tags.
* Use og:video tags for videos.
* Use 720x720 instead of 150x150 preview images for videos.
* Add duration tag to JSON-LD data for videos.
* Add OpenGraph tags to media assets show page.
* Respect Twitter max image size limits.
* Don't include OpenGraph image tags when someone shares a plain https://danbooru.donmai.us link
with no tag search. This caused random potentially NSFW images to be shown when someone shared a
https://danbooru.donmai.us link on social media, which could be cached for long periods of time.
Allow admins to delete media asset files.
This only deletes the image file itself, not the upload or media asset record. The upload will still
be in the user's upload list, but the image will be gone. The media asset page will still exist, but
it will only show the file's metadata, not the image itself. We don't delete the metadata so we have
a record of what the file's MD5 was and who uploaded it, to prevent the file from being uploaded
again and to take action against the user if necessary.
On the show page, add a icon beneath the image linking to the Danbooru post if the asset has been posted.
FIXME: Downstream boorus should change the icon to something else.
Show sources on the media asset show page. An asset can have more than one source if the same
file is uploaded from multiple sites.
Only sources from known sites are shown. Sources from unknown sites aren't shown because they
could potentially contain private information or identify the uploader in some way.
Known issue: Twitter posts often show two sources, the direct image URL and the page URL. This is
because someone uploaded the direct image URL first, and we're not able to tell that the image URL
and the page URL are for the same tweet.
Redesign the media assets show page to:
* Include sidebar with AI tags and image metadata.
* Include next and previous image buttons.
* Make the image use 100% of the available screen space and to scroll with the window.
Add a thumbnail view to the /media_assets page. This page lets you see
all images uploaded to Danbooru by all users (although you can't see who
the uploader is). Also add a link to this page in the subnav bar on the
upload page.
* On the upload page, show the video when uploading a video or ugoira.
* On the upload page, show the filesize and resolution beneath the
image, instead of above it.
* On the media asset show page, show the full video or ugoira instead of
just the thumbnail.
Add a view component for rendering thumbnails for media assets.
This lets us properly show thumbnails on the upload listing page and the
media assets listing page, including support for high pixel density thumbnails
and video length icons for videos.
Fixes not being able to see thumbnails on the /media_assets page.
This is mostly copy/pasted from the post preview component. FIXME: don't duplicate code.
