One of the issues that occasionally pops up for me is that sometimes pictures taken on my iPhone don’t display with their proper rotation in some, non-Apple instances. I encounter this more often with third-party apps, but it still can be an issue. A new post by TJ Luoma over at TUAW — The Unofficial Apple Weblog gives a very interesting, very technical, very geeky way to fix this issue using a utility called jhead. Personally, I prefer to run my images through Photogene on my iPhone, fix any rotation issues and everything is then fine.

This link isn’t presented here so much as a “how-to” but as another peek behind the curtain as to how the iPhone camera works. Note: I’ve found easier and less intrusive ways to fix this issue (see Photogene mention above). If you’re feeling brave, remember that you’re peeking and poking around data. Be sure you know what you’re doing. Always work on a copy of your image. Any time you’re working with the raw code of a file, there’s a chance that you may hose your image.

Apple uses an EXIF tag to rotate images. This can be a problem when you share images with others. Safari will rotate the image correctly, but no other browser will.

Adding to the trouble is that and the Finder will also “auto-correct” the rotation, so it can be hard to tell which images need to be “fixed” and which don’t.
