Meow Lightbox is a Lightbox for WordPress that is made for photographers, by photographers. It works in all circumstances while being light, optimized, and responsive. It displays nicely EXIF information from your image (title, description, camera, aperture, shutter speed, ISO, etc). The layout also adapts itself depending on the image orientation.
If you want to see how it performs, have a look at one of my post on my website, for example, this one: Best Abandoned Places in Japan.
Have a look at Meow Lightbox Pro.
By default, the selector is set on ‘.entry-content’. This selector represents the CSS elements in which the lightbox will look for images and does its magic. Depending on the theme, or what you exactly need, the selector might be different. Check the FAQ below if you are confused.
When you insert images in your posts, make sure the “Link To” is set to “Media File” or to “Attachment Page“.
