Most contact form plugins are built for flexibility, with dozens of field types, conditional logic, integrations, and settings screens. That power comes with complexity, even for the simplest use case.
Micro Contact Form does one thing: it gives visitors a simple way to contact you. The form includes name, email, subject, and message fields. No setup required, no database tables, no clutter.
Add the shortcode [micro_contact_form] to any page, post, or widget and visitors can contact you immediately. Submissions are sent to your WordPress admin email address by default, or to a custom address configured in the plugin settings.
Provides a simple way for visitors to contact you without exposing your email address publicly on your site.

This is a WordPressified version of the excellent, lightweight (for real!) imageLightbox.js (MIT-licensed) by Osvaldas Valutis (http://osvaldas.info/image-lightbox-responsive-touch-friendly)
This is his introduction to the lightbox: 
“As for the image lightboxes, I have always lacked simplicity for them. I mean not only the visual design, but the overall experience: from implementation to UX. All due respect, but I have never liked any of these light-fancy-face-boxes. They all were solving problems that just don’t exist: lots of unwanted features by default, total mess in markup, no native behavior for touch screens. I was working on a project and needed an image lightbox that solves these problems. I needed a lightbox only for images, not video, text, and iframes at once. I made ImageLightbox.js.”
This version autodetects all links to image files and opens them in the lightbox.
For your “install, activate and go”-convenience, this plugin comes with a minimal CSS that easily can be deactivated and/or replaced.
The plugin can also be themed to your liking. An example theme is available here: https://github.com/bjornjohansen/imagelightbox-theme-smooth
