The file name you were trying to upload has been blacklisted because it is very common, uninformative, or spelled in ALLCAPS. Please go back and choose a better file name. When uploading files to Wikimedia Commons, please use a file name that describes the content of the image or media file you're uploading and is sufficiently distinctive that no-one else is likely to pick the same name by accident.
Examples of good file names:
- "City of London skyline from London City Hall - Oct 2008.jpg"
- "1863 Meeting of Settlers and Maoris at Hawke's Bay, New Zealand.jpg"
- "Polyhedron with no vertex visible from center.png"
Examples of bad file names:
- "POLYHEDRON WITH NO VERTEX VISIBLE FROM CENTER.png"
For more information, please see Commons:First steps/Upload form. If you have a good reason for uploading a file with this name, or if you receive this message when attempting to upload a new version of an existing file, please let us know at Commons:Administrators' noticeboard or directly at MediaWiki talk:Titleblacklist. Be sure to specify the exact name of the file you are trying to upload. Thank you.
