My wife and I have used iPhoto 09 to email photos of family to our relations abroad, and have been reasonably happy with the way it enabled one to do this. I bought the upgrade to iLife '11 because of the new easier book creation function. That function is pretty good, I'm happy with it. But we are going to have to return iLife '11 and reinstall iLife 09 simply because iPhoto '11 is a downgrade when it comes to emailing photos. There are now only two options, and both are pretty poor. You can send the original image (i.e., big file size) or you can send the Apple-specified "Optimised" photo. This latter creates a one-megabyte version of your photo, which is all of about 4 inches wide, yet it is at 72 dpi and so you can't enlarge it usefully. Normally the same image size at 72 dpi created say in PhotoShop and saved in jpeg format would weigh in at about 200k max. Why the "optimised" jpeg which iPhoto creates is 5 times the needed file-size is beyond my ability to explain or figure out. The photo is surrounded by an large unwanted and purposeless white border, this is not an option, you have to have it. But even that should not create this large file size.
Where have the other file-size options gone??? In previous versions you could choose from 4 different settings. This so-called upgrade has reduced that to just two options, and neither are useful.
This is a shockingly bad upgrade, and a waste of time and money. Until Apple get their act together, this is software to be avoided at all costs!
I am a multi-decade and committed Apple Mac user by the way. I have never seen such rubbish software emerge from Cupertino before, pretty disappointing to say the least.
