That's a point. I would need to manage EXIF data myself, which was not the case until now.
Perhaps I could find some existing library to do that...
Then, it's not that simple:
- If EXIF data is transmitted for a picture that is to be rotated before vewing it (according to EXIF data), then:
1) If I don't rotate it, it won't be properly displayed on web site
2) If I rotate it, it EXIF data would be wrong, as the picture should now not be rotated any more. To deal with this one, the EXIF data should be updated at this time. Which is probably a good way to corrupt data, when dealing with new kind of camera (or just with bugs)...
What's your opinion, there ?

If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
we don't need the EXIF Info after Uploading so we use pictureTransmitMetadata = false.
I understand the problem if pictureTransmitMetadata == true. A good solution can be to change only the size and rotation part of the metadata.
We want donate for the JPEG-EXIF autorotate feature.
If this feature is included in the Picture Upload a picture should be marked as autorotated and the User should have the ability to change the rotation by overwriting it

About the autorotate feature:
There are several tools to manage this. But I found no opensource library for Java, to do that.
I would be happy to do that, especialy if it's associated with a donation. But I recommand that you do this on server side.
