IPhoto 6 error on import

Question

We are having problems importing photos from our new camera, a Canon A710 IS. We get the following error messages.
The following files cannot be imported (they may be an unrecognized file type or the files may not contain valid data.)
/Applications/A710 Incoming/IMG_0014.JPG
/Applications/A710 Incoming/IMG_0015.JPG
We have nearly a 100 gig of available hard drive space and 1.25 gig RAM.
Last night we read here about rebuilding our iPhoto Library. We tried that and are still having the same issue save for the first 30 image import. We can successfully remove the images from the camera via Image Capture and we are not having a problem using Picassa2 on the PC. iPhoto, however, continues to give this error even if we simply drag and drop from a desktop folder one file at a time.
We are still able to import with no problem with our Canon S1 IS. The file size has increased from 1.3mb to 3.7mb per image between the two cameras.
Help!

Here's a couple of other tests you can run:
1 - create a new temporary library and try to import those files. If they import OK your library may be damaged for some reason. In that case I'd try rebuilding it with iPhoto Library Manager as follows:
Using iPhoto Library Manager to Rebuild Your iPhoto Library
Download iPhoto Library Manager and launch.
Click on the Add Library button, navigate to your User/Pictures folder and select your iPhoto Library folder.
Now that the library is listed in the left hand pane of iPLM, click on your library and go to the File->Rebuild Library menu option
In the next window name the new library and select the location you want it to be placed.
Click on the Create button.
Note: It may take some time to create the new library if you have a lot of photos. One user reported that with a library of about 5,000 images it took about 12 hours so plan ahead.
If the don't import then it may be something associated with your account. Here's two ways to determine that:
1 - log into another account on your G4 and try to import those photos into a library there. Put them in the shared folder from the other account. If you don't have another account it's not a bad idea to create a non-admin account with no special add ons, etc. It's a great trouble shooting tool. If the files import there OK then it's an incompatibility with your primary account.
2 - the second method is to boot into Safe Mode and try importing into your primary library and the temp library.
Good luck.
