I would move this post to the Apple Postprocessing forum and also list how you are trying to upload - card reader, cable, etc.
The photos should have uploaded in a matter of minutes since the total upload would be a little over 3GB. Sounds like a software, driver or card reader issue. Try importing to Aperture and then export to your website. If you're using a cable, try putting the SDHC cards in the built-in MacBook SDHC card reader or get a good USB card reader and try that.
