Better source request for File:Fig retine.png

Thanks for uploading File:Fig retine.png. You provided a source, but it is difficult for other users to examine the copyright status of the image because the source is incomplete. Please consider clarifying the exact source so that the copyright status may be checked more easily. It is best to specify the exact Web page where you found the image, rather than only giving the source domain or the URL of the image file itself. Please update the image description with a URL that will be more helpful to other users in determining the copyright status.

If you have uploaded other files, consider checking that you have specified their source in a complete manner. You can find a list of files you have uploaded by following this link. If you have any questions please ask them at the Media copyright questions page or me at my talk page. Thank you. Sfan00 IMG (talk) 10:08, 11 July 2009 (UTC)

Copying within Wikipedia requires attribution

Thank you for your contributions to Wikipedia. It appears that you copied or moved text from Flash lag illusion into Fröhlich effect. While you are welcome to re-use Wikipedia's content, here or elsewhere, Wikipedia's licensing does require that you provide attribution to the original contributor(s). When copying within Wikipedia, this is supplied at minimum in an edit summary at the page into which you've copied content, disclosing the copying and linking to the copied page, e.g., copied content from [[page name]]; see that page's history for attribution. It is good practice, especially if copying is extensive, to also place a properly formatted {{copied}} template on the talk pages of the source and destination. The attribution has been provided for this situation, but if you have copied material between pages before, even if it was a long time ago, please provide attribution for that duplication. You can read more about the procedure and the reasons at Wikipedia:Copying within Wikipedia. Thank you. If you are the sole author of the prose that was copied, attribution is not required. — Diannaa 🍁 (talk) 13:36, 28 February 2019 (UTC)
