 * Hi all.
 * I have created a custom field for my posts, which is usually a specifically sized
   image, but can also include flash video or embedded audio players.
 * What i would like to do is, use this image in an archive list as a thumbnail.
   I need to
 * 1. Check to make sure it is an image.
    2. If it is an image, resize to 150px 
   square 3. If it is not an image, grab a default thumbnail. 4. From here i will
   style it with CSS.
 * I tried using Justin Tadlocks “get the image” plugin, but it would pull the content
   whether it was an image or not.
 * my site is here: [http://nerdynothings.com](http://nerdynothings.com)
 * I want to take the home page images and reuse on the category archive page, only
   as thumbs.
 * any help would be appreciated.
