This plugin is similar to other image list plugins with one main difference, instead of causing increased server load by searching for and pulling an image from the post it pulls the image from the custom fields specified by the author when he/she writes the post. By doing this a much clearer image can be displayed rather than showing a stretched or skewed image from the post.
