Jim:
First try launching Image Capture and see if you can import the photos to a folder on the Desktop. If you can then reformat the memory card with the camera, take some test shots and try again.
FWIW, my recommendation is to use a card reader for uploading photos from the camera. It avoids several potential problems that could damage the library, e.g. an early shutdown by the camera due to low battery. It's just a much safer way of handling your photos.
TIP: For insurance against the iPhoto database corruption that many users have experienced I recommend making a backup copy of the Library6.iPhoto (iPhoto.Library for iPhoto 5 and earlier) database file and keep it current. If problems crop up where iPhoto suddenly can't see any photos or thinks there are no photos in the library, replacing the working Library6.iPhoto file with the backup will often get the library back. By keeping it current I mean backup after each import and/or any serious editing or work on books, slideshows, calendars, cards, etc. That insures that if a problem pops up and you do need to replace the database file, you'll retain all those efforts. It doesn't take long to make the backup and it's good insurance.
I've created an Automator workflow application (requires Tiger or later), iPhoto dB File Backup, that will copy the selected Library6.iPhoto file from your iPhoto Library folder to the Pictures folder, replacing any previous version of it. It's compatible with iPhoto 6 and 7 libraries and Tiger and Leopard. iPhoto does not have to be closed to run the application, just idle. You can download it at Toad's Cellar. Be sure to read the Read Me pdf file.≤br>
Note: There now an Automator backup application for iPhoto 5 that will work with Tiger or Leopard.
