I did something stupid, and lost all my photos in iPhoto

Question

So, I thought I was in a specific Album with 5 photos in it I wanted to remove from iPhoto. I hit Apple-A to select all and hit delete. It wasn't until a moment later that I realized I must have actually been in my Library, and removed ALL my photos from iPhoto.
Now, all the Albums still appear in the left of iPhoto (6.0, BTW), but when I click on the albums, no photos appear. I went through my hard drives and dragged the appropriate photos back to their original Albums to reimport them into iPhoto. This worked fine with old photos I had organized BEFORE I switched to importing everything in iPhoto.
When I try to import those newer photos, the ones imported through iPhoto over the past couple of years, I keep getting the following error: "The following files could not be imported (they may be an unrecognized file type or the files may not contain valid data)." The files are fine...I'm just trying to import them from their organized roll folder in the iPhoto folder under Photos. Sometimes, I will also get an error that says the file is "already in the iPhoto library."
Is there some kind of preference or something I need to delete so I can reimport these photos from the iPhoto folder into iPhoto again?

EditThis:
If you did not empty the iPhoto Trash via the iPhoto menu the photos will still be in the iPhoto trash container in the Source pane. Click on the trash icon, select all of the photos and drag to the Library icon at the top of the Source pane. They will be returned to their rolls and albums.
The reason you're getting that message is you're trying to import photos that are within the iPhoto Library folder. That can't be done.
