Your Google Business Profile may reject pictures for several reasons, which can affect how your business is presented online. Here’s a detailed summary of potential reasons and troubleshooting steps:

1. Image Quality and Size: Google has specific requirements regarding image quality. If your photos are low resolution or too small, they may be rejected. Ensure that your images are clear, high-quality, and meet Google's specifications for dimensions.

2. Content Violations: Images that contain inappropriate content, such as nudity, violence, or any form of hate speech, will be rejected. Make sure your pictures comply with Google's content policies.

3. Branding and Watermarks: Photos that are overly branded or have watermarks may not be accepted. Google prefers images that represent your business authentically without excessive promotional graphics.

4. Relevance to Business: If the pictures do not relate to the type of services or products you offer, they might be rejected. Ensure that your images accurately depict what your business provides.

5. Type of Image: Specific types of images, such as logos or promotional banners, may not be allowed in certain sections of your profile. Make sure you are uploading images to the appropriate categories – for example, interior, exterior, or team photos.

6. File Format: Verify that your images are in a supported file format, such as JPEG or PNG. Unsupported formats will result in rejection.

7. Violation of Terms of Service: If your account has a history of violations, Google may be stricter about accepting new images. Review your account status and ensure it complies with all guidelines.

8. Resolution Issues: Images that are too large or too small in resolution may be flagged. Google typically recommends images to be at least 720 pixels in height or width.

If you find that your images are being rejected and you have checked all these potential issues, you may want to reach out to Google support for further assistance.

By addressing these areas, you can improve your chances of having your pictures accepted on your Google Business Profile.
