iOS (originally iPhone OS): You can capture the screen on your iOS device using the Sleep/Wake and Home buttons. Press and hold the Sleep/Wake button on the top or side of your iPhone, iPad, or iPod touch, then immediately press and release the Home button. You can find the screenshot in your Photos app
Windows Phone: Press the power button and volume-up key at the same time. If you are having trouble getting the timing just right, hold the volume-up key, and then press the power button.
Mail them to yourself
If you are using an iOS platform, you can reduce the image size by opening the Mail app, composing a new mail, and selecting attach photos. You'll see a prompt that asks if you want to send these images in their original size or in a lower resolution. Pick a lower resolution and email the photos to yourself.
