For a while, rhm's avatar appeared sideways when viewing BikeForums on my phone.
Yes, I have seen this with Apple devices in particular.
The standards for embedding EXIF into digital photos describe bazillions of different fields, most of which are ignored by 99% of the software out there. When an Apple device takes a photo, rather than rotate the photo to match the position in which it is being held, it just alters the EXIF data to state which way the photo should be oriented. So someone looking at the photo on a non-Apple device may see a different orientation than someone with an Apple device.
