I had a feeling I wasn't clear. I will try again. Thanks for your patience and response.
After last update of iPhoto (I think, 9.2.3 Lion), something happened. I remember it was updating thumbnails but I did something which may have caused files to be corrupted (please don't ask, as I can't remember). Now, iPhoto has no pictures. No thumbnail pics and no pics in general. There are captions to each large event as I had originally organized it. But, when I click on a photo, there's that dreaded triangle with an exclamation mark in it. btw, there is no word warning of any kind.
I followed all the steps mentioned in this thread to fix any issues. I even downloaded library manager but that didn't work either (maybe I'm not following process correctly).
I tried importing all the files from the HD but after a while, I get a message that there's no room on iphoto to finish importing. I have three libraries, an original, something else I can't remember and a rebuilt library. It was the rebuilt library I was trying to import. When I open the contents, I see in the info box, 34 GB of space but it says there are 0 files. I look in the files and there are no pictures. Unlike the library I saved into my external HD. I see all my photos there.
So, I decided to create a whole new library. I tried importing all those photos from my external to my desktop but I get the same message of there's no room. So I imported a few at a time and that worked. I have some photos in my new library.
I thought I would throw the old rebuilt library in my HD into trash and I started emptying it thinking that would free up space to put the photos from my external back into the new library. I went to bed but the next morning the trash was still emptying. Then I realized there's still thousands of files on there taking a very long time to empty trash. That's when I stopped emptying trash as I freaked out thinking I might be doing something worse. If it says 0 files, then I don't know where the photos are and why contents shows 34 GB left in rebuilt library. I hope I didn't make matters worse by throwing old rebuilt in trash and then emptying contents.
So hopefully this clarifies my problem. I guess what I'm asking is, can I trash old rebuilt library without hurting anything else. I have the photos on my external if I can trash old rebuilt library to free up space, can I then import the files from external to new library?
