The widget supports up to 4 image sets by default. If you need more, here’s how to add additional ones:
🧱 Option: Add Another Widget Instance
Open your Wix Editor site.
On the left side panel, click the “Add Elements” button.
Navigate to the “App Widgets” section.
Find the Before and After Gallery Widget.
Drag and drop the widget into the section where you want to add a new comparison.
Upload a new 'Before' and 'After' image pair.
This method allows you to stack multiple before-and-after comparisons on a single page — perfect for portfolios, case studies, or makeover galleries.
