I was trying to upload a photo/image to the Amazon-S3 storage, and I am successful with the uploading. In my Amazon-S3 storage does show the file I uploaded. But the problem is the photo I upload is corrupted/crashed, whenever I am trying to open and view the photo from my Amazon-S3. I keep try and error of my coding, but I couldn't find where is the mistake. Thanks.
