When you load a page, then by default all images are loaded and animated ones play on a loop. If constantly moving images are a disturbance for you, you can prevent it with a simple setting change.

To stop images from moving:

1. Click on Toggle images and animation on the Status Bar.
2. For Play Image Animation select either Once, if it’s ok to go through the animation one time, or Never, if you don’t want them to move at all.
3. Reload the page.
