Images rotate when uploaded

I'm not sure how its happened but some of my clients images rotate when uploaded. Sometimes by 180 degrees sometimes by 90 degrees. I've encountered it with other systems before with pics from ipads. You've given an answer before but i was wondering if there has been any way added since, in which I could rotate the images within perch?..

"I suspect the '90 degree' problem is that your computer may be auto correcting the photo orientation for the preview based on the camera's EXIF data. The file is still the wrong way up.

EXIF processing is possible in PHP, but the library isn't commonly available, so it's not something Perch does yet. We hope to add that in the future, but it's lower priority as most people won't benefit from it."
