Understanding the image object
Image object. You can create a new image instance using the
new Image() constructor or by referencing an existing image in the DOM using
Declaring an array to hold images
You start by declaring an array that will hold your images. An array can be declared using square brackets
 or with the
new Array() constructor.
Creating a new image object
To add a new image, create an
Image object and set its
src attribute to the desired image path.
Adding an image object to the array
Once you have an image object, use the
push method to add it to the array.
Working with existing DOM images
If your image already exists within the DOM, you can reference it and then add it to your array.
Using objects to store more information
If you need to store additional information with each image, use an object to hold the image and its metadata.
Accessing images from the array
To work with images stored in the array, you can iterate over the array or access them directly via their index.
For performance, you might want to preload images before adding them to the array, especially if they are not immediately displayed.
Using image storage URLs
It’s common to use hosted storage solutions (like AWS S3 or Supabase Storage) to store media like images. In cases like this, you can simply store the URL to the image in an array:
Uploading an image to your storage solution will depend on the provider you use, but most will have an API or SDK available to upload media like images.
