License tagging for Image:Seq.jpg
Thanks for uploading Image:Seq.jpg. Wikipedia gets thousands of images uploaded every day, and in order to verify that the images can be legally used on Wikipedia, the source and copyright status must be indicated. Images need to have an image tag applied to the image description page indicating the copyright status of the image. This uniform and easy-to-understand method of indicating the license status allows potential re-users of the images to know what they are allowed to do with the images.

For more information on using images, see the following pages:
 * Image use policy
 * Image copyright tags

This is an automated notice by OrphanBot. If you need help on selecting a tag to use, or in adding the tag to the image description, feel free to post a message at Media copyright questions. 20:08, 6 November 2006 (UTC)

How to write numbers
Stop using dots and commas (decimal separators) to facilitate the reading of numbers. Enough is enough.
