Moves the gallery shortcode styles to the head so it doesn’t break XHTML 
validation; allows disabling or modifying the default gallery styles.
By default when using the WordPress gallery, the styles are placed into the 
post content which breaks XHTML validation. This plugin moves the style into 
the head of the page using a look-ahead to determine if the [gallery] 
shortcode is used in any posts.
This plugin also gives you the option to modify the default gallery style 
CSS or disable the gallery styles entirely (so you can control it from your 
template CSS files).
This plugin uses ideas recommended in a patch located at 
https://trac.wordpress.org/attachment/ticket/6380/6380-style.diff

XVE (XVE Various Embed) is a simple yet powerful way to add media content to your WordPress blog. It is a drop-in replacement for my old XHTML Video Embed plug-in, while it aims to continue the original support.
The plug-in is self documented, so there’s the point where you may want to start. The help is integrated into the WordPress help system. If you’re looking for it, it’s into the above menu, the ‘Help’ item. For some of you, this isn’t so obvious as the Help system is kinda new.
New features and support requests are honored better if you open a <a href="https://github.com/SaltwaterC/XVE-Various-Embed" title="GitHub" rel="nofollow ugc">ticket on GitHub</a> where this plug-in is actually hosted.
Supported video services: youtube.com (youtu.be URLs as well), metacafe.com, dailymotion.com, revver.com, spike.com, vimeo.com, livestream.com, capped.tv, trilulilu.ro, 220.ro, collegehumor.com, myvideo.de, snotr.com, gametrailers.com, blip.tv
Supported audio services: trilulilu.ro, 220.ro
Supported image services: trilulilu.ro
It also supports generic SWF / FLV (MP4) embedding.
For the FLV (MP4) embedding, there are three provided players: Flowplayer, FLV Player, and JW Player. You may change them on the fly without the need to change the embed code.
