Choose where pin images come from

Your post's images, stock photos, text-only and list designs, or AI images on your own key, and how to pick per post or for the workspace.

A pin needs a background. Bloomtack can take it from several places, and tries the kinds that suit each post.

The image sources

1. Your post's images: the featured image and the photos inside the post.
2. Stock photos: from Unsplash, Pexels and Pixabay, searched with the post's keyword and title. Their licence and credit are stored with each photo.
3. Text only: a clean background in your brand colors, no photo.
4. List designs: numbered lists, steps or checklists with small icons, made from the post's headings. They need at least three headings.
5. AI images: a background generated from your post on your own AI key, marked "AI". Only offered when your workspace has a key picked for images. See AI images.

The three choices

• Let Bloomtack pick (the default): Bloomtack tries post images, stock photos, text only and list designs, and keeps what works best.
• Post images: pins use only the images that are already in your post.
• AI images: pins use a new image from your AI provider. It bills each image on your own key, and AI pins are labelled as AI.

Where to choose

• For the workspace: open Settings, then Writing. Pin images sets where the images of new pins come from. Owners and admins change it; everyone else can read it.
• For one post: in Posts, open the post's History and use Pin images for this post. Same as the workspace setting puts the post back on the workspace choice.
• When you make pins: the Create pins panel has an Image source row.

A choice applies to pins made from now on. Pins already made keep their images. AI images is greyed out until a key is picked for the AI images task under Settings, then AI keys.

Which one to use

• A food blog with good photos, like Crumb & Kettle: Post images or Let Bloomtack pick.
• A blog with few photos of its own: Let Bloomtack pick, so stock photos and list designs fill in.
• If you want unique backgrounds and have an AI key: AI images, for the workspace or for selected posts.

Good to know

• Bloomtack never uses images from other people's pins.
• If a post has no usable images and stock finds nothing, text-only and list designs still work.
