Resize images with a Slack reaction
Use a familiar approval signal to send a visual asset into the right format without reopening the request later.
Trigger
Message Reaction Added
Triggered when a reaction is added to a message in Slack. Supports optional filtering by channel and emoji name.
Action
Generative Resize Image
Tool to adjust image aspect ratios via generative outpainting. Use after specifying required new dimensions for outpainting.
Why this helps
A seemingly small resize can remain unfinished because it is separated from the image review that identified it.
- Tie the resize handoff to the image message under review.
- Use reactions as a concise signal for a repeatable image task.
- Reduce the chance of a format change falling off the task list.
Setup
Build it in a few focused steps.
- 1Connect Slack and Claid ai once through the portal.
- 2Create an automation or ask Notis to generatively resize an image when your agreed format-change reaction is added, using the needed dimensions from context.
- 3Choose Slack's Message Reaction Added trigger and set a channel for run reports.
- 4Test with an image that needs a specific, real target dimension.
