No Frills Gallery is a simple image gallery with optional slideshow feature. There are a number of gallery plug-ins for WordPress, but many 
are either too complex, too rigid or too expensive for some developer’s needs. No Frills Gallery has been developed for simplicity, but also 
for customisation. Thanks to it’s use of shortcodes, which are generated after you have chosen your specific requirements, both the gallery 
and slideshow can be placed anywhere on the site, either in a page or as part of a sidebar, header or any content area via either the standard 
shortcode or PHP’s do_shortcode syntax.
The styling has remained purposefully simple, allowing you the flexibility you need to build on your own style. All front-end stylings can be 
view in the /css/no-frills.css file. While you can edit this directly, it is not advised as it may be replaced on future plug-in updates. 
Instead simply copy the styles inside this css file and add them to your own theme’s style.css file. Then customise them to suit your needs.

No Frills Gallery

Photection is a plugin to help you prevent image theft by disabling right click on images on your site, without an impact on site usability (right clicks on everything else will still work!).
When an user right-clicks on your image, a small (customizable) message will appear telling him that the image is copyrighted.
Please keep in mind, that no plugin will ever make your images 100% secure. 
There will always be advanced techniques to steal your images, no matter what you do or which plugin you use. Here is an article <a href="https://colormelon.com/image-right-click-protection-plugin/" rel="nofollow ugc">about image protection online</a>, you can read that to learn more.
That said – there is no reason why you should make it easy to save your images, and this plugin is designed to do just that.
