Copy / Upload images from local hosting to Amazon S3 and vice versa

Our client has a website with a lot of client uploaded media. The uploaded media resides on a host server. Due to its popularity it has been decided to upload all user content i.e. the pictures by our users to Amazon [login to view URL] reside on a URL similar to the following [login to view URL] and have the following structure For User 1 user1/pixel/[login to view URL] user1/pixel/[login to view URL] user1/pixel/[login to view URL] user1/original/[login to view URL] user1/original/[login to view URL] user1/original/[login to view URL] user1/modified/[login to view URL] user1/modified/[login to view URL] user1/modified/[login to view URL] user1/modified/[login to view URL] user1/modified/[login to view URL] user1/modified/[login to view URL] user1/thumbail/[login to view URL] user1/thumbail/[login to view URL] user1/thumbail/[login to view URL] user1/archive/archive-2014-03-17/[login to view URL] user1/archive/archive-2014-03-17/[login to view URL] user1/archive/archive-2014-03-17/[login to view URL] For User 2 user2/pixel/[login to view URL] user2/pixel/[login to view URL] user2/pixel/[login to view URL] user2/original/[login to view URL] user2/original/[login to view URL] user2/original/[login to view URL] user2/modified/[login to view URL] user2/modified/[login to view URL] user2/modified/[login to view URL] user2/modified/[login to view URL] user2/modified/[login to view URL] user2/modified/[login to view URL] user2/thumbail/[login to view URL] user2/thumbail/[login to view URL] user2/thumbail/[login to view URL] user2/archive/archive-2014-02-17/[login to view URL] user2/archive/archive-2014-03-17/[login to view URL] user2/archive/archive-2014-06-17/[login to view URL] This runs into thousand of files in that structure. As you can see, the archive folders were generated via a php based on the date that the media was uploaded. Now, our client wants to export these files to Amazon S3 keeping the same structure. Due to limitations set by the host Amazon PHP SDK cannot be used, but the following Amazon S3 Class has to be used -[login to view URL] Likewise, our clients would like to be able to import all the files from Amazon S3 back to their server - again keeping the same file structure. So bascially we require: Part 1 - From local host to Amazon S3 Part 2 - From Amazon S3 to local host The Amazon S3 class is attached.
