</ul>
Follow & contribute to this plugin on <a href="https://github.com/rocket-galleries/rocket-galleries" rel="nofollow ugc">Github</a>.
The modern, straight forward interface is built to fit right into the WordPress admin area. It’s built to feel like native WordPress functionality, not a plugin, which is great for impressing clients and instantly feeling familiar with the plugin’s admin area. Simple, just the way we like it.
Rocket Galleries is also developer friendly. We’ve made it easy to integrate the plugin with your theme by including a template loader. This allows you to create your own gallery templates and use your own HTML, CSS and Javascript easily. We’ve also included dozens of filters and actions within the plugin’s code, allowing you to hook into the core and create your own Rocket Galleries extensions. The possibilities are limitless!
Last but not least, Rocket Galleries is a very new plugin, so we look forward to your feedback. Over the next couple of months we’re hoping to rapidly develop it’s functionality, so feel free to use the <a href="https://wordpress.org/support/rocketgalleries/" rel="ugc">Support Forums</a> to make feature suggestions and feedback.

Media Defaults allows you to specify default settings for inserting media and galleries into posts, pages and custom post types. The following list shows all the items that can have a custom default 
setting:
<ul>
<li>Inserting Media
<ul>
<li>Attachment Filter – display only items “Uploaded to this post” or any other filter, such as 
“Audio” or “Unattached”</li>
<li>Alignment – the default alignment setting for images</li>
<li>Attachment link – what happens when the user clicks on the media item, e.g., “Embed Media Player”, 
“Link to Attachment Page”, “None”, etc.</li>
<li>Attachment Size – the default size setting for images </li>
</ul>
</li>
<li>Adding Galleries
<ul>
<li>Thumbnail link – the destination when users click on an image in the gallery</li>
<li>Number of columns – how many images to display in each gallery row</li>
<li>Random order – whether Random will be selected by default for new galleries</li>
<li>Thumbnail size – the default size when creating new galleries</li>
</ul>
</li>
</ul>
Media Defaults does this in a way that is unobtrusive and integrates seamlessly with WordPress’ 
native interface. See the screenshots for examples.
Media Defaults uses WordPress’ native defaults when installed so you won’t notice any change until you alter the settings to your liking.
Media Defaults does NOT make changes to existing content, galleries or to WordPress’ [gallery] 
shortcode. It only adds new sections to Settings > Media in the WordPress admin area that allow 
you to specify new defaults for creating galleries or inserting media, and implements those 
defaults in the “Add Media” popup screen.
Requires WordPress 3.6 and PHP 5.
