At home I use the wonderful Gallery2Export plugin for Apple's iPhoto photo catalog program into a Gallery2-based online album. It has generally worked great, but yesterday when I was trying to upload Halloween pictures it stopped working. Some fiddling later, including going through the hassle of trying another plugin (iPhoto2Gallery, which also failed), I finally upgraded the website from PHP 4.4 to PHP 5.1, and... it magically started working! Hurray! I've no idea if that was the actual problem or if it was just sheer luck, but its working again and now I can get back to the fun of sharing pics with my family :-)
