File source problem with File:Ad images Page 1 Image 0001.jpg
Thank you for uploading File:Ad images Page 1 Image 0001.jpg. I noticed that the file's description page currently doesn't specify who created the content, so the copyright status is unclear. If you did not create this file yourself, you will need to specify the owner of the copyright. If you obtained it from a website, please add a link to the website from which it was taken, together with a brief restatement of that website's terms of use of its content. However, if the copyright holder is a party unaffiliated from the website's publisher, that copyright should also be acknowledged.

If you have uploaded other files, consider verifying that you have specified sources for those files as well. You can find a list of files you have created [ in your upload log]. Unsourced and untagged images may be deleted one week after they have been tagged per Wikipedia's criteria for speedy deletion, F4. If the image is copyrighted and non-free, the image will be deleted 48 hours after 20:45, 7 April 2011 (UTC) per speedy deletion criterion F7. If the file is already gone, you can still make a request for undeletion and ask for a chance to fix the problem. If you have any questions or are in need of assistance please ask them at the Media copyright questions page. Thank you. Eeekster (talk) 20:45, 7 April 2011 (UTC)
