Before you begin

  • A supported reference image.
  • A precise change and credits for a new image version.

What you’ll achieve: An edit request with a marked area and clear written direction.

Model choices

Area comments can guide an unrestricted image-edit workflow when you use a compatible Less restrictive edit model. The numbered marks identify where to change the picture; they do not change the selected model's policy or guarantee a precise result.

Find your source in Library

Open Library and choose All media. Find the saved image you want to correct, or upload a supported source first. Confirm its thumbnail and name before opening the preview.

Step 1 · Preview Academy character.webp
Tong Image comments interface for “Find your source in Library”, with the Preview Academy character.webp control highlighted by arrow 1.

Open the image preview and select Comment. Localized comments are tied to this source image and are separate from your account profile.

Step 2 · Comment

Mark and describe the relevant area

Click the relevant part of the image, write what should change in the local edit field and adjust Area if needed. Select Save comment. A circle alone does not explain the desired result.

Step 3 · Save comment

Review and submit the correction

Check the localized comments and any overall direction in the composer. Remove an outdated comment if it conflicts with the change, then review the image price before Send prompt.

Step 5 · Send prompt
Tong Image comments interface for “Review and submit the correction”, with the Send prompt control highlighted by arrow 5.

Step 5: Send prompt

A useful tip

A small, specific correction is easier to interpret than several overlapping comments with different goals.

If something goes wrong

If a mark is on the wrong source or region, correct it before generating. Area comments are guidance and do not guarantee pixel-identical preservation outside the marked area.
