image/jpeg: Decode incorrectly complains about missing SOF marker

[opennota]

http://play.golang.org/p/qUNLzBVraB

The image was generated using ImageMagick and libjpeg's cjpeg and is a valid image with a SOF0 marker, but Decode() complains about invalid JPEG format: missing SOF marker.

If I dump your jpg array to file and then try to decode it I get

$ djpeg ~/Desktop/imm.jpg 
Corrupt JPEG data: 3 extraneous bytes before marker 0xc4
Invalid JPEG file structure: SOS before SOF

Are you sure you are using a valid JPEG image?

[opennota]

@ALTree Oops. Something went wrong. Closing the issue as invalid.

For the record, I stumbled across this issue while debugging an image resizer, I had some images that wasn't resized and the error message was the same as this issue, so I tried to get the type of the file and turns out to be png and I forgot to import the png and also gif decoders to my app.

just to save some time for other people who gets here.
