Q: Can't Rotate Photos in my iCloud Folder

I've had the exact same problem D. Chico. But its not just a few. It's most of my photos from iCloud.  I too am runnning Windows 7 64 Bit and have an iPhone 4S.

OK, this is a known iphone 4s .jpeg meta data bug discussed in many threads including this one:

For me, the best answer so far is to install Jpeg Lossless Rotator and integrate it with the system so when I right click on a photo, there are now 'Lossless Rotator Left' and 'Lossless Rototor Right' options to rotate the picture. It works like a charm. Works with multiple pitures at a time.  It's free and you can download it here:

And, what the heck, I did a blog post on how to use the free JPEG Lossless Rotator App complete with a video demo:
