File permission problem with File:Helicity isosurfaces for grid to rod fretting in a reactor core.jpg

Thanks for uploading File:Helicity isosurfaces for grid to rod fretting in a reactor core.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-enwikimedia.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 take this step, add {{OTRS pending}} to the file description page to prevent premature deletion.

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-enwikimedia.org.

If you believe the media meets the criteria at Wikipedia:Non-free content, use a tag such as {{non-free fair use in|article name}} or one of the other tags listed at Wikipedia:File copyright tags#Fair use, and add a rationale justifying the file's use on the article or articles where it is included. See Wikipedia:File copyright tags for the full list of copyright tags that you can use.

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 created in your upload log. Files lacking evidence of permission may be deleted one week after they have been tagged, as described on criteria for speedy deletion. You may wish to read the Wikipedia's image use policy. If you have any questions please ask them at the Media copyright questions page. Thank you. Super Mario Man 03:48, 23 July 2012 (UTC)[reply]

The content of the above message is also relevant to two of your other recent uploads, File:Helicity isosurfaces for fuel rod and support spacer.jpg and File:Ahmed body streamlines at high reynolds number.png, both which you state have previously been published elsewhere. Can you confirm that you personally hold the copyrights to these two images? Thank you. Super Mario Man 03:58, 23 July 2012 (UTC)[reply]
