File:DSCN1486 B-2140.JPG is now available on Wikimedia Commons as Commons:File:China Northern Airlines MD-82.JPG. This is a repository of free media that can be used on all Wikimedia wikis. The image will be deleted from Wikipedia, but this doesn't mean it can't be used anymore. You can embed an image uploaded to Commons like you would an image uploaded to Wikipedia, in this case: [[File:China Northern Airlines MD-82.JPG]]. Note that this is an automated message to inform you about the move. This bot did not copy the image itself. --Erwin85Bot (talk) 02:12, 10 May 2009 (UTC)Reply
File source problem with File:NDB ZBAA 36L MM.JPG
Latest comment: 18 March 20101 comment1 person in discussion
Thanks for uploading File:NDB ZBAA 36L MM.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 uploaded by following this link. 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 14:55, 18 March 2010 (UTC) per speedy deletion criterion F7. If you have any questions or are in need of assistance please ask them at the Media copyright questions page. Thank you. IngerAlHaosului (talk) 14:55, 18 March 2010 (UTC)Reply

Thanks for uploading File:NDB ZBAA 36L MM.JPG. I noticed that while you provided a valid copyright licensing tag, there is no proof that the creator of the file agreed to license it under the given license.
If you created this media entirely yourself but have previously published it elsewhere (especially online), please either
make a note permitting reuse under the CC-BY-SA or another acceptable free license (see this list) at the site of the original publication; or
Send an email from an address associated with the original publication to permissions-en@wikimedia.org, stating your ownership of the material and your intention to publish it under a free license. You can find a sample permission letter here.
If you did not create it entirely yourself, please ask the person who created the file to take one of the two steps listed above, or if the owner of the file has already given their permission to you via email, please forward that email to permissions-en@wikimedia.org.
If you have uploaded other files, consider checking that you have provided evidence that their copyright owners have agreed to license their works under the tags you supplied, too. You can find a list of files you have uploaded by following this link. Files lacking evidence of permission may be deleted one week after they have been tagged, as described on criteria for speedy deletion. If you have any questions please ask them at the Media copyright questions page. Thank you. IngerAlHaosului (talk) 14:55, 18 March 2010 (UTC)Reply

Hi,
This image was seemingly uploaded prior to current image polices, Thank you.
However, as part of ongoing efforts to ensure all media on English Wikipedia is correctly licensed and attributed it would be appreciated if you were able to confirm, that it was your own work, by marking it as Template:Tl, amending the Template:Tl added by a third party, and by changing the license to an appropriate "self" variant. You can also add |claimed=yes to the Template:Tl tag if it is present to indicate that you've acknowledged the image, and license shown (and updated the Template:Tl where appropriate).
