Use a result as the next source | YouThumbAI Documentation

Choose one finished image as the visual starting point for a further change.

How to use it

Choose the finished image

On the result, choose Use as source, or drag it onto Source thumbnail.

Confirm the new source

Check the source tile to confirm the intended variation was selected.

Review the current settings

Review the current prompt, person, references and options; write the change you want.

Describe the change and generate

Keep Default for general refinement, or choose another action after selecting the source. Generate when ready.

What happens

Field or result	After Use as source
Source image	Replaced by the chosen result
Action	Set to Default
Other composer fields	Keep their current values
Original result	Remains in its run

This does not reload the originating run’s settings. Review the current prompt, person and references before generating.

Example

Setup: choose the best variation as your source. Prompt:

Keep this composition; make the background darker and preserve the product.

Check the result: compare the background and product with the source, then inspect the rest of the image for unintended changes.

Good to know

This is an AI iteration, not a pixel-perfect edit. Inspect the entire output. If you want the original run’s settings rather than its finished image, reuse the run.
