The fetched image is not ideal for my content

Sometimes, the image that the app fetches may not be the perfect match for your content. It happens.

To replace the image, you would need to:

1) Get an image directly from Pixabay or Pexels (or any other source).

2) Upload it to your site's media library (Posts & Pages > Media).

3) Click on the existing featured image which you want to replace (right sidebar of the post editor) and replace it with the new image. Save the post.
