iPhoto 5.0.4 Flips Photos Properly -- Apple has released iPhoto 5.0.4, a minor update that "addresses an issue with browsing photos that have been auto-rotated by a camera." Honestly, I've not seen the problem (it seems to relate to editing photos that were auto-rotated by your camera and that appear in the wrong orientation), but the speed with which 5.0.4 followed 5.0.3 means that it's probably bugging a bunch of people. The update is roughly 40 MB via Software Update or as a standalone download. [ACE]
Better Text Formatting in iPhoto
If you're creating a card or book in iPhoto, and you're not happy with the formatting options for the text (such as line spacing or justification), copy the text out to TextEdit, make the changes you want there, and paste it back into iPhoto, which will retain your changes.
