I'm writing to share my experience with uploading photos to Facebook using the built-in integration with the Photos app and sharing accounts. For the most part it works great, but it seems that any photos taken with the internal camera that are portrait-orientation show up in Facebook in landscape (sideways). Has anyone noticed this behavior?

I'm tempted to think it's Facebook's fault, because sharing the exact same photo in the exact same way with Flickr or via email yields a properly oriented photo. However, I'm not 100% sure of this.

Try using pixelpipe - I've had no problems at all with that.
