If the flashing images in video games have given you seizures, chances are that other on-screen viewing experiences are potential seizure triggers, too. By making some adjustments to your monitor and browser, you can limit the visual stimulation delivered by computer images.
This list is hardly comprehensive, but it includes some basic approaches to protection against unwanted flashing and animation in the Windows environment. Please contribute additional suggestions!
You can lower the brightness settings on your monitor to reduce contrast and effects of flash. This setting is different on each device/monitor—on my Dell laptop, to lower the screen brightness I hold down the Function key while pressing the up arrow on my keypad.
Desktop and color scheme
In Windows, go to the Settings menu, Control panel > Display.
Don’t select one of those constantly moving designs as a screensaver
Choose default or low-contrast color schemes
Block unwanted Flash videos
Firefox: Download the extension Flash Block at https://addons.mozilla.org/en-US/firefox/addon/flashblock/?src=search
Flash Block prevents automatic display of moving sequences that are powered by Macromedia Flash or Shockwave. When you load a page containing these images, a placeholder appears on the screen in the spot where the image would be displayed. To view a blocked image, just click on the placeholder.

Stop animated images from moving, as needed for individual screens
Unless you disable them, animations that blink or automatically cycle through images will stay animated for as long as you stay on any page. To prevent graphics from animating in your web browser window, once the web page has stopped loading and the images start to animate, just hit the ESC key on your keyboard.
That will immediately disable all the GIF animations on that webpage. In order to replay the animated images, reload the page by pressing F5 or Ctrl+R. This feature is already available in most browsers, but not in Google Chrome.
To activate the ESC key option for blocking animation in Chrome, download a browser extension at http://userscripts.org/scripts/show/80588
Prevent animated images from moving, automatically for all screens
Firefox: Download AniDisable extension. See
Internet Explorer: Tools > Internet Options > Advanced. Uncheck the box in the Multimedia list that says “Play animations in web pages”
Chrome: This option is not currently available.
