What leaves your site
Every way of sharing your work sends something out of your site, and no two channels send the same thing. One carries a blog excerpt. One carries a link. One carries an image. Knowing which is which is what makes the switches easy to set.
Four channels
What each one carries
RSS
Blog posts, as an excerpt or roughly the first 500 characters of HTML, plus a link. It's a feed of writing, not a photo feed.
Link previews and embeds
A card (title, short text, one image) from Open Graph, or an embed where the other site reads oEmbed. Hiding a page from search doesn't remove either.
Share buttons
Your URL and nothing else. A visitor opens Facebook, X, or LinkedIn with the link filled in, and the network builds its own preview from your page.
Open Web Distribution
The only channel that sends a copy of the image: a public JPEG up to 2048 px with copyright metadata, the caption, and a link home.
Four payloads, one table
| Channel | What travels | Where a copy lives | What you can pull back |
|---|---|---|---|
| RSS | Excerpt and link | Feed readers and aggregators | Edit or delete on your site. A reader may keep what it already fetched |
| Link previews and embeds | A card (title, short text, one image), or an embed where the other site reads oEmbed | The app or site that fetched it | Fix the page, then each platform refreshes on its own schedule |
| Share buttons | A URL | Nothing from you | Same as link previews and embeds |
| Open Web Distribution | Image, caption, link | Every server that received the post | A Delete is sent. Removal elsewhere isn't guaranteed |
Each channel is its own switch
ArtInStack keeps these separate on purpose. Turning on RSS doesn't turn on Open Web Distribution, and neither changes what a pasted link looks like. Sharing buttons are off until you want a collection to travel, and stay off when it should feel like a quiet viewing room. Each channel does one job, so you can match the channel to how your audience already behaves.
Email Center campaigns are a separate channel again: a list you chose, on a schedule you set. They are not RSS, Open Graph, or Open Web Distribution. See Built-in email or a separate tool.
Previews and embeds are fetched, not sent
You never push a preview or an embed anywhere. When someone pastes your public URL, the chat app or editor fetches the page: Open Graph for a card, oEmbed when the host wants a richer embed. That's why either can lag behind a fix: each platform holds its own copy and refreshes it on its own schedule. The docs page on link previews has the refresh steps. Search visibility is a separate system, which is why hide from search leaves the card and the embed path intact. See Hide from search, noindex, and private.
What stays home, in every channel
Vault links and private-portfolio files are kept out of these channels on purpose. RAW files and originals never go out, only the public web derivative. Nothing is published outward unless you chose it.
What none of this controls
These channels describe what you send. They don't stop anyone from saving a public image, and they don't govern crawlers. The site's robots.txt today allows crawling and points to your sitemap; there are no AI-crawler controls. Treat anything you make public as copyable, and let that decide what goes on a public page.
Know what travels before you switch it on
Four channels, four payloads. Only one sends a copy.
