This plugin shows images as thumbnails below the teaser-text of a post. Only images are shown, that are not contained within the teaser-text, so visitors can have a teaser of further images of the post along the teaser-text and may not overlook some beautiful photos that are not displayed in the teaser-text on the home page.
The plugin only contains one line of displayed text, but it’s already translateable. If you want to use it in another language (that’s not currently supported), feel free to contact me so I may extend the languagefiles.

Add a short teaser text with page thumbnail and link it to a page in your sidebar. The plugin takes care of correct linking. I am using the plugin on my own <a href="http://www.jonaspiela.com/" title="Jonas Piela" rel="nofollow ugc">website</a>.
