WP7 -以图像形式发布的表单。

I need to send an image from the Windows Phone 7 to some e-mail addresses. I use this class to submit text values to a PHP script, wich parses data and sends a formatted e-mail to the addresses. The problem is that I can't figure out how to send an image to that script, to attach the image to the e-mail. The PHP script can be changed in any way. If I have an Image object, how can I change this class to allow sending images?I need to send an image from the Windows Phone
