The Image Modal plugin adds a modal lightbox effect to images within the post content, allowing users to view larger versions of images without leaving the post.
This plugin requires NO settings, NO subscriptions, NO trials or pro versions. It just works out of the box with any image on the content of your posts or pages, either if it was Attached to the media library or just pasted from clipboard.
When an image is clicked, a modal box will appear with the larger version of the image. Dismiss the modal box with the close button or clicking on the modal’s background.
<h3>Requirements</h3>
NONE, but to show a pointer cursor when hovering on the images, his plugin requires that your content div in your theme has the class “.entry-content”. Chances are that this is the case if you are working with a relatively modern theme.
<h3>Licensing</h3>
This plugin is released under GPLv2.

FooBox adds a lightbox to your WordPress site, so images are loaded in a modal or popup instead of redirecting your visitors away from your site.
Some people often refer to a lightbox as an “Image Zoom” effect. It’s really just a modal overlay or popup that showcases your images.
FooBox was the first lightbox to take responsive layout seriously. Not only does it scale images to look better on phones, but it rearranges it’s button controls to look great in both portrait or landscape orientation.
Add a modal popup to your website images with no setup. FooBox will automatically add modals to WordPress galleries, WordPress images with captions, and attachment images.
Works with most image gallery plugins, but works best with our <a href="https://fooplugins.com/foogallery-wordpress-gallery-plugin/" rel="nofollow ugc">FooGallery Gallery WordPress Plugin</a>.

Complete FooBox Asset Control
By default, FooBox lightbox includes javascript and stylesheet assets into all your pages. We do this, because we do not know if the page content contains media or not. 
If you want more control over when FooBox assets are included, you can now exclude the assets by default, by enabling a setting. Then on each page, you can choose to include them when required. 
Alternatively, you can leave the setting disabled, and then choose to exclude the FooBox assets from particular pages. A new metabox is now available when editing your pages or posts. 
This new feature was only available in the PRO version beforehand, but we feel control over your website performance is something you should not have to pay for. Enjoy!

Lightbox & Modal Popup WordPress Plugin – FooBox


it´s easy to get going right after the install! not too complex as I am needing it for "single" images to lightbox! really excellent!!!!!!


wonderful!

stops working after 7 days


FooBox works great ouf of the box (pun intended) and is well-suited for sites that need a quick image lightbox plugin that plays well with others.



The default lightbox theme provided is professionally made and well-suited for showcasing screenshots, portfolio items, photography, and more.



If you need more layout choices and compatibility with even the peskiest lightbox plugins, please check out Pro, as it's the only license I don't hesitate to renew.


FooBox is fantastic
