I also, over time, have seen longer load times for iPhoto. I have a couple of thoughts on this. When I had my iPhoto library in my G5, it snapped open quickly, never an issue. Then I went to Snow Leopard on a newer Intel Mac Pro. I don't remember any load time problems, but there was a short load time on open. Then I upgraded to Mountain Lion. Now I'm seeing long load times. But I can't state that it was the upgrade to Mountain Lion, because as time went by, I also grew the library. It's annoying waiting for everything to load, it's gotten up to 15 seconds now. When you want to just jump in and work with something you just put in, you have to watch the spinning beach ball. Note, that when you click the window to close iPhoto, it actually quits the program. It doesn't just go sit in the background, so when you reopen, it has to load again. Although that may free up RAM, if you have a lot of RAM in the machine, which I have enough at 8GB, it wouldn't be a problem to have it ready and waiting. So, I would ask Apple, if you want to close the program with the window, then how about you give an option in preferences to load just the last 10% of the library rapidly, and slowly load the rest in the background, while allowing immediate use such as viewing or editing the most recent? Solution #2: I don't know if Apple loads the library photos in iPhoto trash as well. If they do, you might consider emptying your trash there. If that doesn't help, you can burn your older photos to a disc like a DVD which will hold a boatload, then trash the photos in iPhoto. Now your library is smaller, and should load faster. If you want those photos back in for any reason, you can simply drag them off the disc back into your iPhoto window again, and they will be back. I wouldn't do it in the iPhoto library folder directly, where iPhoto stores the photos, that will probably screw up your indexing or cause some other unforeseen problem down the road. As an alternate for photo editing, for those of you not familiar with Graphic Converter, it deserves a good look. It's a reasonably priced shareware program that gives very powerful editing features. It's fast, and sometimes I just use that to resize, improve, run filters, etc.. It's earned the nickname "The poor man's Photoshop". After using it for several years, I've come to really rely on its features. You can run it for free in demo and decide if you like it. It puts a progressive timer on the front end to open. It has full functionality once you get in. By the time the timer becomes annoying, you should have figured if you like it enough or not to go ahead and purchase it.
