Re: Is sending pictures to your email a good way to preserve them forever?
Just save the picture to a folder on your device (in most browsers, you right-click and select "Save", "Save as" ect.), then upload it as an attachment to an email with your own email adress as the person to send it to.
There are better ways, but if you wish to focus on your email, then that is how you go about doing it.
Have you had a look at Dropbox? That is what I use, and it works very well. It will explain exactly how to use it when you install the software.
