Create an administrative interface allowing administrators to upload assets (such as images) to a page or post. The current version is a developer-centric plugin and is not recommended for users not comfortable editing page templates. I do hope to update the plugin in the future to add short-code placement of the asset listings.
Plugin uploads the files from WordPress media upload directory to AWS S3 bucket and replaces their initial URLs with the new URLs of AWS S3 bucket (changes src attribute).
