How can I make smaller images on my Webflow portfolio pages expand to a larger scale when clicked on, like a pop-up window?

To create a pop-up window effect for smaller images on your Webflow portfolio pages, you can use Webflow's built-in lightbox functionality. Follow these steps to achieve the desired effect:

1. Select the image that you want to make expandable and go to the Settings panel on the right-hand side of the Webflow Designer.

2. Under the "Link Settings" section, click on the Link field to open the Link Settings modal.

3. In the Link Type dropdown, choose "Open Lightbox."

4. By default, the lightbox will use the image's original size, but you can customize this if needed. To do so, you can upload a larger version of the image by clicking on the "Choose" button in the "Lightbox" section of the Link Settings modal.

5. After uploading the larger image, you can configure additional options like Captions, Alt Text, and Thumbnail in the Link Settings modal.

6. Click Save to close the Link Settings modal.

7. Now, when you preview or publish your site, clicking on the smaller image will trigger the lightbox effect, displaying the larger image in a pop-up window.

By using the Webflow lightbox feature, you can create an engaging and interactive experience for your portfolio visitors, allowing them to view your images in a larger scale without leaving the current page.
