One bad slide shouldn't cost you the whole carousel. Versely has three separate per-slide operations for exactly this: replace_slideshow_slide regenerates a single slide from a new prompt, remove_slideshow_slide drops one, and reorder_slideshow_slides changes the running order.
Each of them works on a specific image_id, so the practical first move is always get_slideshow — it returns the slides with their ids and current order_index, which is what turns 'the fourth one' into something the tools can act on.

Replace a single slide in a slideshow with a freshly generated image. Use when the user asks to regenerate, swap, or replace a specific slide (e.g. 'replace slide 2 with a sunset', 'regenerate the 4th image', 'redo slide 1'). Charges credits for the new image (refunded on failure). Drops any stale text-overlay version of that slide. If you don't have the image_id, call get_slideshow first.
What to tell the agent
Versely's agent maps this plain-English request directly onto replace_slideshow_slide. You don't need to know the parameter names — just describe what you want.
“Show me my slideshow, then regenerate slide 2 as a sunset shot and move the last slide to the front.”
How it works
1. Look at the actual current state
get_slideshow returns the live slideshow with each slide's image_id and order_index. Slide N is the Nth image after sorting by order_index ascending — work from the fetched state, not from what the conversation said earlier.
2. Replace the slide that's wrong
replace_slideshow_slide takes the image_id plus a new prompt (and optionally a model) and generates a fresh image in that position.
3. Or drop it entirely
remove_slideshow_slide deletes a single slide. Note that it does not refund credits — the image was already generated.
4. Fix the running order
reorder_slideshow_slides takes the COMPLETE new ordering as image_id / order_index pairs — every slide, not just the ones that moved.
What it costs
Replacing a slide charges for the new image (refunded on failure), because it's a fresh generation. Removing a slide refunds nothing — the image was already made. Reordering doesn't generate anything. So the cheap fixes are reorder and remove; replace is the one to think about before you run it on eight slides.
The formula behind that number: What does a batch of 100 AI product images cost? — charges one fixed price per call, so the image's size and shape are free.
Limits & things to know
- remove_slideshow_slide does not refund credits for the deleted image.
- reorder_slideshow_slides needs the full ordering, not a diff — omitting the slides that didn't move is the most common way to get an unexpected result.
- Replacing a slide drops any stale text-overlay version of that slide, so re-run add_text_overlay afterward if the set was captioned.
- These act on a slideshow, not on a rendered video. If you already ran convert_slideshow_to_video, fix the slides first and re-render, rather than editing the MP4.
Who uses this
- Swapping one off-brand image out of an otherwise finished carousel
- Dropping a slide a client rejected without regenerating the set
- Moving the strongest image to slide one after seeing them together
- Fixing a slideshow before it goes out as a scheduled post
Frequently asked questions
Do I get credits back if I delete a slide?+
No — remove_slideshow_slide does not refund, because the image had already been generated. Replacing a slide charges for the new image, and that charge is refunded if the generation fails.
How do I reorder just two slides?+
You still pass the complete ordering. reorder_slideshow_slides takes every slide as an image_id / order_index pair, so call get_slideshow first to get the full current list.
What happens to text I'd already added to a slide I replace?+
The stale overlay version of that slide is dropped, since it belonged to the old image. Re-apply add_text_overlay after the replacement.
How do I identify a specific slide?+
By image_id, which get_slideshow returns alongside order_index. Slide N is the Nth image once you sort by order_index ascending.
