Thumbnails Manager helps you to manage your thumbnails within the administrator panel. You can define a default ratio for thumbnail creation, rename, change the description or even delete your thumbnails.
This is the very first time I release one of my own plugin. Maybe because it is a little bit more finished than the previous ones even if I can?t say I spent a lot of time on this one.
Well? In other words, be indulgent and please give me helping comments and any wish for the next version.
A small list of features:
<ul>
<li>Change the default ratio for the thumbnails.</li>
<li>Display images by pages.</li>
<li>Rebuild thumbnails.</li>
<li>Rename and change the description.</li>
<li>Resize of thumbnails.</li>
<li>Delete of images.</li>
<li>Thumbnails creation size strategy: scaling, maximum size, fixed size</li>
</ul>
New in v0.7:
<ul>
<li>Thumbnails creation size strategy: scaling, maximum size, fixed size</li>
<li>A bug correction (impossible to save ratio value)</li>
</ul>

The Custom Admin Branding Plugin allows you to brand and customize the WordPress administration area for clients or for personal use. You can display custom images and styles for the login screen, admin header and footer.
It should be fairly easy to use for anyone familiar with WordPress and has basic css and html skills. At its simplest it only requires you to activate and then replace three images with your own. Photoshop templates are included to help you with that.
