images showing up sideways when posted from iPhone/Android

it appears that images are showing up sideways when posted from an android or iOS device. Funny thing is it appears normal when viewing the website from the device but not from a PC. I think this is a known problem:

I know it's Ghost, but the problem is with the EXIF data in the photos.
I'm not much a .net programmer - or any programmer really - is there an option to correct exif data?
