Images from Wikimedia Commons
Just an FYI: This wiki has an extension which allows usage of images from Wikimedia Commons, the free media repository administered by the Wikimedia Foundation. Instead of downloading and re-uploading images, you may simply copy the file name from Commons and paste it here at the wiki.
For example, to add this picture to the wiki, all you have to do is copy the file name ("File:Monterey Historics 2011-10-41 - Flickr - Moto@Club4AG.jpg") and click on the image button on the edit toolbar (which appears while actively editing a page), paste the file name, then click on "insert". Once the page is saved, you will see the image, like you do to the right.
