Seeding multiple image attachments from Amazon S3 in Rails

Question

 am trying to seed multiple image attachments to a model. I have been using this link but I am still sort of stuck since what I aim to do differs a little since:

1. I am trying to attach multiple images to each object (which I seed) in the model
2. I want to retrieve these images from my S3 bucket and attach them to the objects (is this possible?)

Here's my seed.rb:

shirt = Item.create(name:"Basic Shirt",price:19.99)
skirt = Item.create(name:"Basic Skirt",price:29.99)
sweater = Item.create(name:"Basic Sweater",price:39.99)
kid_hood = Item.create(name:"Basic Kid Hoodie",price:19.99)

# somehow attach images here?

I am using the aws-sdk-s3 gem in order to connect Active Storage to my S3 bucket. Please tell me if any additional files are needed for viewing. I will happily edit this post to include it.
