01 Load images
2–10 images. Instagram carousels cap at 10.
02 Crop for Instagram
Optional, but recommended — without this, Instagram will auto-crop mismatched images itself and you won't get to choose what's kept. Pick a ratio, then drag each image to frame it. Both originals and crops are sorted into ratio-named folders in your R2 library when you save this carousel for review.
03 Preview the carousel
Use ← → or click the edges. Keyboard works once you click the frame. Shows the cropped version once you've applied one.
04 Caption
Edit the prompt sent to Gemini
05 Schedule
06 Save for review
This does not post anything yet. It saves the carousel to your review queue below — you approve each one by hand before it ever reaches Buffer. Images (cropped or original) are saved into your R2 library, sorted by aspect ratio.
07 Pending your review
Nothing here has been sent. Approve a carousel to queue it — immediately if Buffer has room, or held in the waiting pool if it's full.
08 Waiting for a Buffer slot
These were already approved by you — they'll be sent automatically the moment a slot opens up.
