You can build an Unsplash clone or free-to-use Shutterstock with Bubble's no-code platform, starting by registering your free account and following introductory lessons to get familiar with the basics of Bubble. You'll then need to create a visual design for your platform using Bubble's visual design tool, configure your database with necessary data fields, and start building workflows to power your application. The main feature to build is a function for users to upload and publish photos to the platform, which includes adding input elements, creating a workflow to trigger when a user clicks the publish button, mapping relevant on-page input elements with corresponding database fields, and displaying dynamic content in a feed. Other key features include displaying full images within a repeating group, downloading an image, searching for photos, sending data between pages, and following another user. With Bubble's no-code platform, you can build your own photo-sharing app or utilize core features from a stock photo platform without any additional costs, starting from as low as $25 per month.
