- For Internet Explorer (IE) users: Press the 'Stop' or 'Esc' button on your keyboard or Go to Tools & Internet Options, click on the "Advanced tab", then go to "Multimedia", now un-check the "Play animations in web pages" option and finish by clicking the "OK" button.
- For Firefox (FF) users: Press the 'Esc' button on your keyboard or Go to your browser's "about:config" then search for "image.animation_mode" then change the value to "once" this will just play the animated GIF once, click OK or Save or Finish button.
- For Opera users: Press [F12] on your keyboard then un-check the "Enable GIF/SVG animation" in the option.
- For Konqueror 2.2.x users: Right click on it and select "Stop Animations"
or To completely block ALL animations in any website you load, go to your browser's "about:config" then search for "image.animation_mode" then change the value to "none" if you however change your mind and now you want to see the animated GIFs go back to "about:config" then search for "image.animation_mode" then change the value to "normal".
or Try the flash blocking Firefox addon on Firefox. All animations based on Adobe Flash will be blocked this way, the commonly used one is the "FlashBlock" add-on (flashblock.mozdev.org) which stops flash files from loading automatically.
As I said before, this works ONLY with animated .gif images, it may not work with other flash, banner, ad or logo. You will benefit much from Firefox's image & ad block addons which works on an array of images.
