Arduino Webcam Capturing Storage Problem

Hi Guys! My name is Jacky Ang, I am newbie in Arduino.
Recently I was decided to make a security system, one of those features are webcam capturing which mean it will captures picture when the user are typing wrong password.

But i wonder that how to save these picture? Do I supposed to adds a memory card or ethernet shield so it can access to website?

Currently I am using the GSM Sim900 to send notification message to owners, it's capable to send email so it can attach and send these picture to owners?

Please help~thanks

I suppose you could add three servos, instead, and have the Arduino move a pen around to draw a picture.

But, adding an SD card seems far simpler.
