I can't install my license! Step by step procedure, with screenshot, is here.
I can't log in! Once in a while, I've had trouble logging in: weird web pages from Facebook display, or I get stuck in a loop between two sign in screens, or I stay stuck as the previous user even after logging out and in. If this happens to you, it may help to sign out of Facebook in Safari if you are signed in on the web. If that doesn't help, try using the Reset Safari... option in Safari to Remove all Cookies. And feel free to let me know about the problem.
Will the license work with upgraded versions? Yes, the license is for all 1.X versions. I suppose someday I might do a dramatically new version 2.0 that would require the purchase of a new license, but not for a while if ever.
Strange flickering; two of the screen savers run at once. If you use the Test button to run the screen saver, but the screen saver was also previously set to start after a short time, you may find that the test saver continues to run while a second copy runs as well, with unpleasant flickering between the two. Or, you may find that the screen saver engine crashes and you are returned to system preferences with nothing running. I believe this is a bug in Snow Leopard. If you have your screen saver set to run automatically after a delay, I recommend that you avoid the Test button. You can always set up a "hot corner".
How do I uninstall? Lion users can use the minus button in System Preferences. Leopard and Snow Leopard users should go to Library/Screen Savers in Finder, and drag AmiPhotos.saver to the Trash. On those older OSs, if you want to remove all traces (this is not necessary), go to Library/Preferences/ByHost, and drag com.davidmcnerney.AmiPhotos.blah to the Trash. If you installed a license, then you can go to Library/Application Support and trash the AmiPhotos folder as well.
