This image was originally uploaded to English Wikipedia by Gizelle (an employee of the Hanson Company) under the GFDL license and she named it "Hanson steelwatertank.jpg", on September 20, 2006. Someone objected to the fact that the image had the Hanson Company name painted on the tank. On October 6, 2006, I used Microsoft's Paint program to removed the Hanson Company's name and I re-uploaded the image under the name "Modified Hanson steelwatertank.jpg" and overwrote the original image. I retained the same GFDL license that had been selected by the original uploader. The modified image has now been in use in 2 Wikipedia articles for two months. I am now uploading the modified image into Commons and will retain the original GFDL license.
