Faster Image Insert aims to do one thing right:
Moves built-in Media Manager down in a meta-box, right next to main editing panel, so you have full control of the manager: opens it, makes it collapse or hidden from the interface completely.
Best of all, is now you can insert image(s) much faster, and precisely where you want them to be.
<ul>
<li>No thickbox, using metabox with zero interface blocking, quite similar to the uploader in WordPress 1.5</li>
<li>No hacking, default upload interface is not affected, only enhanced.</li>
<li>Insert multiple images in gallery & library mode, without using shortcode; can also insert images in reversed order, and even control spacing between images.</li>
<li>Mass info editing, change title/captions in one-shot.</li>
<li>Smart switches: set default uploader, disable captions.</li>
</ul>
This plugin is designed for:
<ul>
<li>Screenshot lover – movie, game or anime review etc.</li>
<li>Howto guru – cooking guide, hardware DIY guide etc.</li>
<li>Photo logger – author can comment below each photo.</li>
<li>Blogger that has been shouting “run, thickbox, RUN!” to the loading screens.</li>
</ul>

With <a href="https://github.com/pixelgrade/pixcodes" rel="nofollow ugc">PixCodes</a> you can have a shortcode insert interface.
The awesome part is that you can filter any shortcode parameters or overwrite any shortcode template with your theme.
Note: this plugin does not add any style to the output of shortcodes.
We believe that shortcodes functionality should be offered by a plugin and the style should be provided by themes.
Here is a <a href="http://github.com/pixelgrade/pixcodes/blob/master/README.md" rel="nofollow ugc">detailed documentation</a> about how you can configure some plugin settings and output.

PixCodes

PixCodes offers you a nice interface to add shortcodes into editor.
