How to Enlarge Images from Gallery of Thumbnails in Bubble.io

Introduction

In this tutorial, we will learn how to create a "click-to-enlarge" feature for images in your Bubble.io app. This functionality is essential for improving user experience, especially in applications that showcase images, such as galleries or listings. By following these steps, you can ensure that users can easily view images in detail, making your app more user-friendly and visually appealing.

Step 1: Set up the Image Gallery

• Create a Repeating Group: Start by adding a repeating group element to your Bubble.io page. This will serve as the gallery for your thumbnail images.
• Add Image Elements: Inside the repeating group, insert image elements that will display your thumbnails. Make sure to link each image to its corresponding larger version.

Step 2: Create the Popup for Enlarged Images

• Add a Popup Element: From the design tab, insert a popup element where the enlarged image will be displayed.
• Insert an Image Element in the Popup: Within the popup, add an image element that will show the larger version of the image when clicked.
• Set the Image Source: Ensure that the image source of the popup is dynamically linked to the image that was clicked in the gallery. Use the "This Image's URL" expression for this purpose.

Step 3: Configure Workflow for Image Clicks

• Create a New Workflow: Go to the workflow tab and create a new workflow that triggers when an image in the gallery is clicked.
• Show the Popup: In the workflow action, choose to show the popup you created in Step 2.
• Set the Image Source: Add an action to set the image source of the popup to the clicked image. Use the "Element Actions" to specify the image to be displayed.

Step 4: Test Your Setup

• Preview Your App: Use the preview mode in Bubble.io to test the functionality. Click on different thumbnails to ensure that the corresponding enlarged images appear in the popup.
• Check Responsiveness: Make sure the enlarged images are displayed correctly on various devices and screen sizes.

Conclusion

By following these steps, you have successfully implemented a "click-to-enlarge" feature for images in your Bubble.io app. This enhancement not only improves user experience but also makes your application more competitive in the market. For further improvements, consider adding features like image captions or navigation between images in the popup. Happy building!
