Easy Image Sizes For WordPress is a very simple plugin that allows you to create an unlimited number of different image sizes and them alongside the builtin ones (ie. thumbnail, small, medium etc)
When an image get uploaded through the WordPress media manager (including the featured image option), WordPress creates variations of said image at different sizes for use in different scenarios. I am sure you will have seen the option to select either thumbnail, medium, or full size when inserting an image into a post or page. This plugin simply adds to the list of automatically generated sizes available.
Features:
<ul>
<li>Create an unlimited number of image sizes</li>
<li>Custom sizes automatically appear in the media manager for inserting into posts</li>
<li>Images sizes are available for the featured image/post thumbnail</li>
<li>Have WordPress crop or scale the image</li>
<li>Set cropping positions (ie. top, bottom, right etc)</li>
<li>Uses all native functionality for a smooth experience</li>
</ul>

Easy Image Sizes

Good thing!

Remarkably easy to use (after some initial confusion on my part from not reading the instructions).

I created an image size to be used with a list of posts.  When I looked at the list of posts, the images were displayed in their expected sizes.  Easy peasy!

Easy Image Sizes allows you to configure different WordPress image sizes and use them alongside the standard ones (ie. thumbnail, small, medium etc)
