First things first, make sure your Adalo project is up and running. You can either start fresh with a new screen or pick an existing one where you want to add the image picker.

Head over to the left sidebar and hit the "+" icon to open up the components list. Type in "Image Picker" and drag it onto your screen. Easy peasy.

Click on the Image Picker component on your screen. Now, you can tweak the properties like button text, style, and alignment from the properties panel on the right. This way, it’ll blend in perfectly with your app’s design.

Decide where you want the images to go after they’re picked. You can bind the image source to a database collection or set it up to store the image in a specific data record using the right actions and relationships.

Now, let’s define what happens once an image is picked. Maybe you want to update a user's profile picture or show the image on the screen. Click on the Image Picker component, go to the Actions tab, and specify what should happen when the image is selected (e.g., Update Database, Display Image).

Time to see it in action! Preview your app and select an image to make sure everything works as expected. Check if it updates databases or displays the selected image correctly.

If you run into any hiccups during testing, go back to the Image Picker settings and tweak the configuration, styling, or actions as needed. Keep testing until it works like a charm.

Once you’re happy with how everything’s working, go ahead and publish the changes. Now your users can enjoy the new Image Picker feature!
