Create thumbnails on upload

Jul 10, 2009 at 8:25 AM

Is there any best practice how you can create thumbnails out of the images being uploaded directly to Amazon S3? I will give an example -

User uploads 50 MB Jpeg to(5000x2500 pixesl) to  Amazon S3 bucket using the Direct Uploader - say, "Image.jpg"

At complete time I want to have 2 more thumbnail files (say, "Image_thumb.jpg, "Image_mini_thumb.jpg") that have the main image resized to , say, 100x50 and 50x25 pixels.

I want to avoid subsequent request from server to Amazon to get the image as bitmap, since the files will be very big and the process will be slow.


Kind Regards,
