Hello,

please try this solution it will be helpful for you and resolve the issue.

To upload PNG, JPG, and JPEG files to an S3 bucket with the correct Content-Type using Terraform,

1. first configure your AWS provider with the appropriate region.

2. Then create an S3 bucket and ensure its name is globally unique.

3. Next, upload your image files to the bucket, specifying the correct Content-Type for each file: image/png for PNG files and image/jpeg for JPG and JPEG files. Additionally, set the access control list (ACL) to public-read if you want the objects to be publicly accessible.

4. This setup ensures that your files are served with the correct content type, allowing them to be properly handled and displayed when accessed.

please look at Terraform document Link & AWS Document link you will get more information.

AWS S3, the Content-Type is a metadata field that specifies the media type of the object being stored. It is essential for browsers and applications to correctly handle and display the stored objects. Here are some common Content-Type values for different file extensions:

For HTML files: text/html

For PNG images: image/png

For JPEG images: image/jpeg

For JSON files: application/json

For JavaScript files: application/javascript

For CSS files: text/css

For plain text files: text/plain

For XML files: application/xml

For your specific case, if you are uploading .png, .jpg, and .jpeg files, you should use the following Content-Type values:

For .png files: image/png

For .jpg and .jpeg files: image/jpeg

```
Here is an example of how to specify the Content-Type for these file types in Terraform when uploading objects to an S3 bucket:

resource "aws_s3_bucket" "example_bucket" {
  bucket = "example-bucket"
}

resource "aws_s3_bucket_object" "example_png" {
  bucket       = aws_s3_bucket.example_bucket.bucket
  key          = "example.png"
  source       = "path/to/local/example.png"
  content_type = "image/png"
}

resource "aws_s3_bucket_object" "example_jpg" {
  bucket       = aws_s3_bucket.example_bucket.bucket
  key          = "example.jpg"
  source       = "path/to/local/example.jpg"
  content_type = "image/jpeg"
}

resource "aws_s3_bucket_object" "example_jpeg" {
  bucket       = aws_s3_bucket.example_bucket.bucket
  key          = "example.jpeg"
  source       = "path/to/local/example.jpeg"
  content_type = "image/jpeg"
}

```
aws_s3_bucket resource creates the S3 bucket.

aws_s3_bucket_object resources upload the files to the S3 bucket and specify the Content-Type for each file based on its extension.
