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.

Media Defaults

Set site-wide defaults for creating galleries and inserting media.
