Key takeaways
- Bluesky posts support up to four images per post.
- Add alt text to every image — it matters for accessibility and reach.
- A scheduler that supports Bluesky natively can queue multi-image posts ahead of time.
- Check your images against Bluesky’s current size and aspect-ratio limits before you schedule.
How to schedule Bluesky multi-image posts
Bluesky supports attaching multiple images to a single post, which renders as a grid or carousel in the timeline rather than one image per post. This is useful for before/after shots, product photos, or a short visual story you want viewers to swipe or scroll through.
As of Bluesky’s current image-post format, a single post can carry up to four images. Check the platform’s current limits before you plan a campaign around this, since image and post limits on any platform can change over time.
Step 1 — Prepare your images
Gather the images you want in the post and check them against Bluesky’s current size and format requirements. Keep the images in the order you want them to appear, since most schedulers preserve upload order in the resulting carousel.
- Up to four images per post
- Consistent aspect ratio across images looks cleanest in the grid
- Compress large files so upload and load times stay fast
Step 2 — Write alt text for each image
Bluesky lets you add alt text to every image individually. Beyond accessibility, descriptive alt text helps the post make sense to anyone using a screen reader or browsing with images off, and is good practice regardless of which platform you post on.
Step 3 — Schedule the post
In a scheduler that supports Bluesky, compose the post, attach all your images at once (rather than as separate posts), fill in alt text for each, write your caption text, and pick a publish date and time. Review the preview before confirming — most tools render a preview of the grid so you can catch ordering issues early.
- Attach all images in one post, not as separate scheduled posts
- Fill in alt text before you schedule, not after
- Use the preview to confirm image order and cropping
- Set a publish time that fits your existing Bluesky posting cadence
FAQ
- How many images can you post at once on Bluesky?
- Bluesky’s current image-post format supports up to four images per post. Check the platform’s current documentation before planning a campaign, since limits can change.
- Can I schedule a Bluesky post with multiple images in advance?
- Yes, as long as your scheduling tool supports Bluesky’s multi-image format. Attach the images to a single scheduled post rather than scheduling each image separately, so they publish together as one carousel.
- Do I need alt text on every image?
- It is not required by Bluesky, but it is strongly recommended. Alt text makes each image accessible to screen-reader users and describes the image when it fails to load, and most scheduling tools let you set it per image before the post goes out.
- Will the images post in the order I uploaded them?
- Most scheduling tools preserve upload order in the resulting post, but always check the preview before scheduling — if your tool allows reordering, confirm the final order matches what you intended.
