How can I prevent newly saved images from replacing previously saved images in Firebase?

To prevent newly saved images from replacing previously saved images in Firebase, you can use unique file names for each image. One way to achieve this is by appending a unique identifier to the filename, such as a timestamp or a random string.

Here's an example code snippet in JavaScript, using the Firebase Storage SDK:

// Get a reference to the Firebase Storage service
var storageRef = firebase.storage().ref();

// Generate a unique filename using a timestamp
var filename = Date.now() + '.jpg';

// Upload the image file to Firebase Storage
var uploadTask = storageRef.child(filename).put(file);

// ...rest of the code

In the above code, we're using the Date.now() function to generate a unique timestamp for the filename. You could also use other methods to generate unique identifiers, such as Math.random() or a UUID library.

By using unique filenames, each new image upload will create a new file in Firebase Storage, rather than overwriting any existing files with the same name.
