Field name: "image" with type "Image" -

Field name: "description" with type "Text" (optional)   Step 3: Design the Gallery Page     - Go to the Design tab. - Drag a Repeating Group element onto the page. - Set the Type of content to "Image" and Data source to "Do a search for Images." - Add the Image element inside the Repeating Group cell. - Set the Dynamic Image source to "Current cell's Image's image." - Optionally, add a Text element inside the Repeating Group cell for descriptions. - Set the Dynamic Text to "Current cell's Image's description."   Step 4: Make the Gallery Responsive     - Click on the Responsive tab. - Adjust the page layout to make it responsive: - Ensure the Repeating Group element is set to have a fixed width. - Set the Repeating Group's layout style to Full list for better control over responsive behavior. - Adjust margins and paddings to ensure proper spacing between images. - Go to the Appearance section of the Repeating Group. - Use custom CSS if needed to ensure the cells adjust in size according to the screen size.   Step 5: Add Image Upload Functionality (Optional)     - Go to the Design tab. - Add an "Input" or "FileUploader" element for users to upload images. - Add a workflow to handle the file upload: - When the upload button is clicked, create a new entry in the "Image" data type with the uploaded file. - Make sure to test the upload functionality to verify it works as expected.   Step 6: Add Styles     - Go to the Styles tab. - Define styles for your gallery elements including: - Text colors and fonts for the image description. - Border and shadow for the Image elements to create a polished look. - Apply these styles to the corresponding elements in the Design tab.   Step 7: Preview and Test the Gallery     - Click the Preview button to see how your gallery looks. - Adjust any elements in the Responsive tab if they aren't displaying as expected. - Make sure the gallery looks good on different devices and screen sizes. - Test uploading images (if added) to ensure the entire functionality works seamlessly.   Creating a responsive gallery in Bubble.io with these steps ensures you have a user-friendly and visually appealing interface.
