How do I e-mail pictures from my LG Xenon?

I'm going camping and I want to take the pictures off my phone so I can take more. I have a USB cable, but I CAN'T figure out how to put the pictures on my computer. I hear a lot of people are having the same problem. So I got a tip on my phone (from AT&T) saying to e-mail them to my computer for safe-keeping.

But if I go to my photos gallery, and open the options, there's a send option, but I can only send it via "Message", "Bluetooth", or send it "To HP's Snapfish".

Then if I open a new e-mail to send from my phone, I can't find an option to insert anything.

How do I put pictures in an e-mail??

OR...If you know how to take them off my phone with the USB cable, that would be greatly appreciated too.

I do not own a Micro SD Card.

Thanks in advance for anyone who answers!
