Nut, you are indeed loose. These days, file size is VERY important. Megapixels are not a good indicator of quality, but more of filesize. If you check around with any recent camera software, you will almost certainly find an option for emailing. There are some colossal filesizes generated for even a high quality JPG, as opposed to RAW file, (as I said, my own are up to 7MB) but a simple operation will cut them to >250KB and that is what you want. Bandwidth and inbox capacity are what you need to consider these days.
