on iOS 6, iphone, I get a bug where it only shows me a fraction of the image I'm uploading in the preview. Does anyone know why this is? I had the same issue with jQuery-File-Upload.

I assume you mean the black bar problem? It's a bug in iOS when you try to resize images client size. There's no workaround (besides disabling client-side image processing for iOS) AFAIK.

I've heard that https://github.com/stomita/ios-imagefile-megapixel works around the issue. I haven't had a chance to try it personally, yet.

This is nice. Anyone know if it will work for direct uploads to S3?

I've been playing with browser uploads for a few weeks now (including S3) and was too worried about the complexities of uploading to S3.

I realized that there's nothing really fancy going on when uploading to S3. That's only true since Amazon added CORS support. Just add a few hidden form fields and you're good to go.

Properly populating those fields can be a bit tricky, however. This gem will does a great job and should give you a head start: https://github.com/waynehoover/s3_direct_upload
