If you are the copyright holder and the creator of the file, please read Commons:But it's my own work! for tips on how to provide evidence of that.

The file you added has been deleted. If you have written permission from the copyright holder, please have them send us a free license release via COM:VRT. If you believe that the deletion was not in accordance with policy, you may request undeletion.

Only the author can authorise publication of their work under a Free licence. "Providing a Free licence" does not mean that you simply have to invoke a licence, it entail providing the licence chosen by the author, as well as proofs for it. I have re-deleted the image, please do not upload it again unless you have legally valid evidence that the author has agreed to publish it in the exact licence that you are quoting. Thank you.

SVG (Scalable Vector Graphics) edit

 
 
Please use SVG
Thank you for uploading some images! Did you know that Wikimedia Commons recommends the SVG (Scalable Vector Graphics) format for certain types of images? Scalable Vector Graphics are designed to look appropriate at any scale, and SVG images are easier to modify and translate, helping Wikimedia to distribute knowledge to all of the world. A lot of modern programs support SVG export. If you encountered problems or have questions, don't hesitate to ask me, a member of the Graphic Lab, or the Graphics village pump. Uploading images in SVG format isn't mandatory, but it would help. (To avoid any misunderstandings, please don't just put raster images into an SVG container as embedded raster.) Thanks, and happy editing!
