How to export entire iPhoto library to external hard drive
My iPhoto library had 77,000 photos which is making iPhoto run very slow. I did a one on one training last week and they showed me how to move the library over to my external hard drive. I did that and it took 2+ days because there were so many files. Now that I have moved the library over, how (and should I) do I delete the iPhoto library from my computer, create a new library for May 2009 and beyond, etc so my computer will run properly. I hope this makes sense. Any input would be really appreciated.
Thanks
