Visual LightBox
Is it possible to add a Contact Form to image gallery plugin?
Q: I need a way to be able to click on a picture and have that picture open up to be able to fill out a form for customers. Is that possible with this program, if I purchase it?
A: Free version provides all features and options of purchased version except "Watermark" option.
You can set any html code as a caption for the image, for example add <form> tag:
<form action="URL" method="get">
First name: <input type="text" name="fname"><br>
Last name: <input type="text" name="lname"><br>
<input type="submit" value="Submit">
</form>
where "URL" specifies where to send the form-data when a form is submitted.
You can get more information about <form> tag here:

Notice, VisualLightBox will not generate code that will process data from your form (VisualLightBox can control appearance of your form only). You should do it by yourself.
