Move the Library.
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.
It's already on my external because that was the only way to store (go forth and multiply) my pics and music and documents.
This is my set up. I boot iPhoto (library is on HDD external) as well as all my pictures except the ones I download off the internet. Those are moved weekly or so. My iTunes and music is on my external HDD along with every single document, paper etc I have written since I had my Apple 2GS and all the conversions to Microsoft back to whatever and the original and Pages copy. I'm scanning my deceased mother's medical records also.
I need the space the actual pictures are taking up. Should I move some to my laptop and see if iphoto notices they are not on my external HDD??

Why are you downloading images to the internal if you're then going to move them? Why not download them to the external?
Which disk are you trying to make space on?
Are you running a Managed or a Referenced Library?
A Managed Library, is the default setting, and iPhoto copies files into the iPhoto Library when Importing. The files are then stored in the Library package
A Referenced Library is when iPhoto is NOT copying the files into the iPhoto Library when importing because you made a change at iPhoto -> Preferences -> Advanced. (You unchecked the option to copy files into the Library on import) The files are then stored where ever you put them and not in the Library package. In this scenario you are responsible for the File Management.
I use a managed library.
The downloading is if I find something on the internet like a graphic to save I just download it to my downloads folder on my internal drive. Then I copy them to my external HDD.
If I am using Firefox, it is set to ask where I want to download it. I just use the downloads folder.
Safari just defaults that way.
What I am trying to do is figure out if I can delete my actual files from my EHD after I've imported them into iPhoto because I use a managed library. I know it copies them to the library. I just don't wanna do it if I am gonna lose cherished memories. Everything is on my EHD since my laptop is only 64gigs. I also wanna know this because when I import photos I have to go thru all 60,000 of them because I don't remember which ones are new or not. If I have run Duplicate Annilator it reimports those and imports them off my iphone and ipad.
You how when you import from your iphone or ipad it asks if you want to delete the imported pics. That's what I am wanting to find out. If I can delete my actual files or run a test to see if I move a few out of my Photos folder on my EHD if it will know that they are gone.
