Media Grid and Contact form 7

I am using the Media Grid plugin and Contact Form 7 plugin. Media grid uses a lightbox which I have placed a link to a request info page. The link in the media grid passes the post title to the contact form 7. What I would also like to do is have this link bring the featured image for that particular post to the request info page, sort of like a shopping cart image. Right now this is what is in the lightbox to get the name of the image to the contact form.

<li id = "info">
		  <?php
		 echo '<a href="https://69.195.124.104/~martiob8/request-info?work='. $post->ID .urlencode(get_the_title($post_id)) .'">Request Info</a>'; ?>
		  	</li>

Is this enough to get the image on to the linked page or do I need to pass something else? Then once I pass this what do I need to do to catch it on the request info page. I know it’s possible and probably pretty simple, but for some reason I’m not figuring it out.
Thank you in advance for any help.
