You can create a vertical slider for using an Image comparison section, unleashing the creative potential of your site.
Using an **Image comparison** section can bring you several benefits such as:
* boosting engagement on your Shopify store through interaction;
* creating compelling visual stories;
* showcasing impressive or persuasive presentations.
After [adding the section](/foxify-app/legacy-editor/sections-and-presets.md#add-a-section), you can then customize it to your liking 🌟
## Add a Section header
To the Section header, you can add an image, a heading, or a text child block.
## Customize the Image comparison slider
In the **General settings** > **Images** settings, add your before and after images for a comparison effect. You can also set your images on desktop and mobile view separately.
