| // This file demonstrates file upload to an S3 bucket. This is for using file upload via a | |
| // link compared to actually having the image file content. If you are doing it via image | |
| // file upload, like getting the file from $_FILE, refer to this: | |
| // https://gist.github.com/keithweaver/70eb06d98b008113ce97f6148fbea83d | |
| // | |
| // You must setup your bucket to have the proper permissions. To learn how to do this | |
