Hey Fred,
If the photo contains exif data and EasySocial is configured to import these EXIF data, we would then be able to determine the orientation of the photo. However, it looks like you have turned off the option to "Import EXIF data" and this is why it can't determine the photo's orientation.
Could you try switching on the "Import EXIF data" settings and try uploading the photo again? If it fails, could you please upload the photo to your FTP and provide me with the link so that I can test it?
