Adjusted image navigation. 

You can use the < and > on the main product image to go to the previous/next image. Additionally, you can also open the lightbox overlay and click < and > there (or use keyboard arrow keys) to navigate. By default, using the < and > buttons will skip images with a content advisory. You can turn this off (see "Added more content advisory features" below). 

In the future, we want to make the image thumbnails (below the main image) automatically scroll to which thumbnail is currently being displayed.

Limited the height of main image to fit your monitor. 

Before, you had to scroll to see the full image if it was too long. Now, it'll be a smaller image that fits your monitor. If you want to see it full size, you can click on the main image and it'll open up the original image size.

Added more content advisory features.

If you try to view an image with nudity, the website will show you a warning. You can click the "Hide warning and show image" to see the image and hide future warnings. To re-enable this warning, there's an icon in the top right of content advisory images that you can click.

The website will remember your choice for whenever you view a product image, however, this setting is based on a cookie! If you use a different browser or clear your cookies, you'll be shown the warning again.

In the future we'd like to make it a setting in your user account, but it's cookie-based for now (time constraints, other priorities to fix, blah blah).

Moved sidebar next to main image.

This provides faster access to important information (price) and important buttons (add to cart, etc.) and fills the empty space next to the main image.
