These, as most of my photos, are taken with my phone, a Sony Ericsson K800i. (3.2 megapixel).
As the phone has no optical zoom, I tend to crop and tweak them a bit, using Google's free photomanagement suite, Picasa.
I recommend Picasa wholeheartedly. It's easy to use, and outperforms some other systems, it has Email tools and web albums built-in. And no, they don't pay me anything for this commendation.
The drawback to the phone is SonyEricsson's diabolical software interface, which took forever to install on my computer, and often crashes it. It has conflicts with other device drivers, and frequently crashes Windows XP Pro.
My previous Sony phone, a K750i had none of these problems... connect to the computer and the phone drives are mapped as external storage devices.
This one....
Well, sometimes it works okay.....
And when it's in 'Data Transfer Mode'... the phone part is disabled. How very annoying....
