OpenGraph Images
When you share a published edition, its page includes OpenGraph and Twitter card metadata. The title and description come from the edition’s preserved content, and its preview image is available at /p/{publicationId}/{version}/og.
Which Image Is Used?
Section titled “Which Image Is Used?”Deckyard uses the first image in the edition’s stored content, in slide order. If there is no suitable image, the preview address redirects to the instance’s default card.
The preview is not a newly rendered screenshot of the first slide. The former publication controls for refreshing a preview or adding an author overlay do not change an edition’s preview.
Changing a Preview
Section titled “Changing a Preview”- Edit the source deck’s content or images.
- Open Share > Public and choose Publish new version.
- Share the new edition’s link.
The previous edition keeps its original content and preview. Its address never switches to the newest edition.
Check the Result
Section titled “Check the Result”Open the edition’s /og address to inspect the image, then share the edition’s public page URL. Social platforms choose their own cropping and may cache cards they have already fetched. Publishing a new edition gives the page and preview new addresses.
If the preview is the instance’s default card, check whether the edition includes an image. If the page returns 410 Gone, its author has withdrawn it.
Withdrawal
Section titled “Withdrawal”Unpublish withdraws all public editions of the deck, including their preview endpoints. Deckyard serves edition resources with Cache-Control: no-store, but cannot remove copies already fetched by a social platform or another recipient.
