                     The page contains a GIF image that may cause the screen to
                     flicker. 
                     <br>
                     Make sure the page does not contain an animated GIF with a
                     refresh rate of between 2 to 55 frames per second.

                     Make sure the page contains no animated GIF with a refresh
                     rate of between 2 to 55 frames per second. In other words,
                     make sure no image repeatedly flashes or changes from dark
                     to light from 2 and 55 times per second.

                  <p>
                     If you need to use the animated GIF, increase its refresh
                     rate to more than 55 frames per second or change its colors
                     to reduce the flickering effect.

                     A flickering or flashing screen may cause seizures in users
                     with photosensitive epilepsy. As a result, content
                     developers should avoid causing the screen to flicker.
                     
                  </p>
                  
                  
                  <p>
                     Seizures can be triggered by a light flickering or flashing
                     2 to 55 times per second, with peak sensitivity at 20
                     flashes per second with quick changes from dark to light.
                     
                  </p>
                  
                  
                  <p>
                     Too much animation GIFs may also distract some users from
                     reading the page.
