In your current layout, there are three columns in the row. Increasing the width of this module may not look good visually within this structure.
Based on your current setup, you can add 2–3 images horizontally within the existing column. If that works for you, let me know—I’ll provide the CSS for it.
However, if you want to display all the images in a full-width row horizontally, you’ll need to create a separate position for it. You can follow this documentation for guidance:
