Make sure the drive is formatted Mac OS Extended (Journaled)
1. Quit iPhoto
2. Copy the iPhoto Library from your Pictures Folder to the External Disk.
3. Hold down the option (or alt) key while launching iPhoto. From the resulting menu select 'Choose Library' and navigate to the new location. From that point on this will be the default location of your library.
4. Test the library and when you're sure all is well, trash the one on your internal HD to free up space.
Be sure to use a wired connection. If you're trying to edit the Library (that is, make albums, move photos around, keyword, make books or slideshows etc.) or edit individual photos in it via Wireless be very careful. Dropouts are a common fact of wireless networking, and should one occur while the app is writing to the database then your Library will be damaged. Simply, I would not do this with my Libraries.

And do not put the iPhoto library (or any other dynamic file) on the same volume as your Time Machine backup - sooner or later TM will fillthe volume and your files will have no space to be used

I use this method for my iphoto and have run into a peculiar issue this poster may wish to cinsider before using this method:
I keep my iPhoto library in an external drive (iomega 1 TB) and I use Time Machine (Time Capsule) for my back-up of iphoto. The external drive is failing. I have bought an new external drive and wish to restore my iPhoto library to this new drive. The steps for restoring from Time Machine require me to click on the iphoto library and then enter time machine. I cannot do this as the folder is now unreadable in the drive and I do not wish to restore it to this old drive in any event.
I have accessed the time machine drive and can see the iphoto back up is there.
What is my next step?
