Right then...Tamer......I think I've sussed it out.
iPad on iOS 6 works sweet as a nut,likely to work on iPod touch and iPhones running latest software also.
Take your photos and save them to the device's album,trying to take a pic and upload directly while posting gives rotation and occasional kb oversizing problems.
Go into the album and select the image to upload.
Click edit and rotate either 90 or 180 degrees and save......isn't important first rotation.
Select edit again and rotate until image is the right way up......and save again.
(May seem a drag but its quicker than taking pics,upload to computer,edit rotation and size in a photo editor then search the file to upload)
Doing it this way in the device album will set photo's the right way up and to the correct size to upload 4 pics at a time every time.
