ytimg.com stands for '''Y'''ou'''T'''ube '''im'''a'''g'''e. Images from YouTube, like thumbnails and icons come from that domain. If you're constantly nagged to accept cookies, you've probably set either Firefox or Flash Player to "ask me every time". Both Firefox and Flash Player can be configured to always accept cookies from a particular domain, or to always reject them. To configure Firefox's cookie settings, see * [[Enable and disable cookies that websites use to track your preferences]] To configure Flash Player's cookie settings, open the Windows Control Panel, type ''flash'' into the search box in the top right corner, then click the Flash Player icon in the search results.<br> The Flash Player settings manager is also where you can set camera and microphone permissions. By default, sites need your confirmation before being able to use them. You can either deny permission to all websites without being prompted, or specific sites only. * [http://www.macromedia.com/support/documentation/en/flashplayer/help/settings_manager.html http://www.macromedia.com/support/.../settings_manager.html] * http://adobe.com/go/flash-player-settings-storage
