Sounds like that would be too much for email to handle. If your supervisor has a website, you can ask if you can upload to his website, and he can download from there. Or you could use drop box and he can retrieve them from there. If your pics are on the camera SD card, you might just drop the card off to him. He would need an SD reader that plugs into a USB on the computer. They're fairly cheap, less than $20 in many big box variety stores.
