Don’t know what is going on but it appears that AnythingSlider is stretching pictures that are used as slides. First place I looked was at the image dimensions but I have those same pictures in a gallery in another section of the site.
When I look at the `#slider` element, I see it is being effected by two files:
1. `anythingslider.css` sets the slider dimensions to 1080×720.
2. `theme-metallic.css` set the slider dimensions to 960×540 (overriding the anythingslider.css)
You don’t need both files to add a theme to AnythingSlider.
Also, because the default options are all being used, the `resizeContents` option is set as `true` and forces all images to resize to fit the slider dimensions. If you want to have images of different sizes, make sure to set each image width and height and change the `resizeContents` option to `false`.
