Captcha image position problem

Hi,

i need help to positionate the captcha-type-in-field left beside the captcha-image more higher. The upper line of the captcha-type-in-field, the captcha-image and the send-button should conclude on the same height.

Here the link to the page: http://www.proxpand.com/kontakt

Where is the mistake?

Thanks in advance, Tobias
