Images Appear Right Aligned on Mobile

All my images stick to the right side of my screen on mobile. How do I set the image alignment for mobile?

On mobile, images should usually be full-width automatically.  When you place an image in a blog post, make sure that you just use the WordPress default editor to set the alignment to center.  If that doesn’t fix it, then you probably have some CSS from a previous theme or a plugin that’s causing the images to appear right aligned.
