If images are found that are in breach of these terms they will be removed from search and the public view.
If there are images on your account that have been 'flagged' for any reason, when you're logged in to your account you'll see a message letting you know which images have a problem and giving you more information and what steps you need to take.
In the nearly all cases, this is due to images being uploaded with an existing personal watermark. To fix this problem simply delete the image with the personal watermark and re-upload the image after you've created a new un-watermarked version.
If anything isn't clear or you need more information, please don't hesitate to contact us at firstname.lastname@example.org.
