pictures turned sideways

I took some photos recently using PhotoBooth. let's call the original version A. using iPhoto I changed them to version B, turned 90 degrees.

when I uploaded one photo to the web version A got saved, twice. I figured that had to do with the software of the website. however, when I decided to make a version B photo a desktop image, it appeared as Version A, i.e. before I altered it. I had by this time deleted the actual Version A. I made the iPhoto Version B photo the desktop.

can I correct this? also, does my description make sense?

There are two ways to rotate a photo: one way actually changes the pixels, in short it really does rotate the photo. The second way does not change the pixels, but simply makes an entry in the metadata for the file that says "view me as rotated" so that no pixels are harmed in the process. Apple, responding to complaints of somebody or other, has largely gone to the second method as the default behavior. Anything that can read the metadata will display the rotation, a program that doesn't read the metadata does not display the rotation (Safari for instance).

If you really want the rotation to be actually applied you need to rotate the picture in a program such a Photoshop or Graphic Converter, or if you only have Apple's own graphics programs you need to export the file, not just save it, after applying the rotation.

Photos rotated in iPhoto are actually rotated - as the test in Safari proves. If you rotate them in the edit window, Safari sees the change once you've clicked done on it. On the Organise window there's no notification of the change, no progress bar, but after 15 seconds or so, dragging the thumbnail to Safari will give you the rotated pic. Plus, regardless of which ever way you do it, once you rotate the Revert to Original command becomes available, as you're now viewing the modified version.

Preview is an app that doesn't actually rotate, but only flags the pic.

Hi Terrence, Glad to hear that iPhoto will apply a rotation "for real." Image Capture is another one that doesn't--it used to. Now when you open them in Photoshop after importing they display as rotated (Image Capture reads and preserves the camera's rotation metadata, and Photoshop can also read it and act accordingly), but you now need to do the extra step of actually applying the rotation before programs such as Safari will display them the way you want. With Preview I don't think there is any way to actually apply the rotation (anyway I haven't been able to).

Personally I find the whole issue confusing, and I think others do too. I sidestep it all by first processing in Photoshop.
