Plupload (javascript uploader) directly to Amazon S3(repost)(repost)

A working Plupload implementation of a direct upload to S3 using unique filenames and a callback ## Deliverables I need a working plupload script which can do this: - Runtime: flash and html5 - select up to 500 images (jpeg,jpg,png) - queue them (you can use the default plupload queue example) - on adding files, i need an alert with x files added, x files total in queue (callback: FilesAdded) The files need to be resized on the clientside using plupload's own function: resize : {width : 450, height : 450, quality : 75} The files need to be uploaded directly to a Amazon S3 Bucket and need to be renamed to a unique filename. This new filename (or object key as it's called by amazon) consist of /img/xx/[login to view URL] Where filename is a 50 characters long (a-z,A-Z,0-9) unique generated string and xx are the first two characters of the filename and the correct file extension. So for example /img/G4/G4ak92jdksSD939a....................jpg Upon succesfull upload the new filename (object key) needs to be posted to an url, so we can process it. This just needs to be a plain thing like [login to view URL] If upload isn't succesfull (for whatever reason) it must retry the file up to 5 times. After 5 times it must stop the queue BONUS POINTS: I don't know if it's possible, but if you can also calculate the MD5 of the resized image just before uploading and also post this to the same url. Please use Plupload ([login to view URL]) or convince me of another flash/html5 uploader which can do the same. I can set you up with a test S3 bucket if that's needed.
