<p>No Frills Gallery is a simple image gallery with optional slideshow feature. There are a number of gallery plug-ins for WordPress, but many<br />
are either too complex, too rigid or too expensive for some developer’s needs. No Frills Gallery has been developed for simplicity, but also<br />
for customisation. Thanks to it’s use of shortcodes, which are generated after you have chosen your specific requirements, both the gallery<br />
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<br />
shortcode or PHP’s do_shortcode syntax.</p>
<p>The styling has remained purposefully simple, allowing you the flexibility you need to build on your own style. All front-end stylings can be<br />
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.<br />
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.</p>


No Frills Gallery

A very simple, easily customisable image gallery. Uses shortcodes to display your picture gallery and/or slideshow.
