If you ever wanted to insert a (random) thumbnail of another post or a gallery of thumbnails anywhere in your post(s), page(s) or even in your sidebar or footer without the use of a bulky gallery plugin that might not be compatible with your theme or another plugin you installed, thumbnails anywhere is for you.
Download from the Official WordPress Plugin Repository

Quick Overview

Thumbnails anywhere can display post or page thumbnails (Featured Images) OR an image referenced in a post or page via a custom field.

Thumbnails anywhere can be inserted literally anywhere in your content without having to edit the code. And because it uses shortcodes, no PHP code plugin is necessary either.

We packaged it with timthumb (http://code.google.com/p/timthumb/) to give you utmost control over the output.

Prerequisites

WordPress (obvious)
A theme with thumbnail support and shortcode support in sidebar and footer
If your theme does not support thumbnails or if your theme displays the plugin’s source code in the sidebar or the footer, add the following lines of code to your theme’s functions.php file:

For thumbnail support add:

if ( function_exists( 'add_theme_support' ) ) { 
  add_theme_support( 'post-thumbnails' ); 
}

For shortcode support in sidebar and footer add:

add_filter('widget_text', 'do_shortcode');

Usage

If you want to use an image referenced via a custom field, simply create a field named full_image_value and enter the RELATIVE URL to your image into the value field e.g. /path/to/you-image-file.jpg.

Absolute URLs can cause issues especially on WordPress installations hosted on hostgator.

Note: If you are using a WordPress MU (Network installation), you must use the custom field option as mod_rewrite will not translate the path to your post thumbnail at that stage.

Thumbnails anywhere works by interpreting WordPress shortcodes and shortcode attributes.

[randomimg] – triggers execution of the plugin
If not other arguments are given, thumbnails anywhere will display 2 thumbnails from randomly selected posts.
Default output size of the images (if no argument are given) is 100×100 px.
PrettyPhoto argument already built-in, requires PrettyPhoto to work properly.

Arguments:
w (in pixels) – the desired width of the image
h (in pixels) – the desired height of the image
cat (ID of the category(ies); e.g. cat=”3″ or cat=”3,5,7″) – one more categories to select thumbnails from
post (ID of the post to extract the image from; e.g. post=”70″) – select image from one particular post
css (e.g. “padding:5px; border:1px solid #efefef”) – add your personal styles to the output
showlink (e.g. showlink=”1″ to show the link) – show the title of the post and create a link to the post underneath the thumbnail image.
num (e.g. num=”5″) – the number of images to display

Examples:
[randomimg post="70" w="250" h="170" showlink="1" css="padding:10px; border:1px solid #efefef"]
Shows 1 image taken from the post with the ID 70, 250×170 pixels with a link to the post and a style of “padding:10px; border:1px solid #efefef” applied.

[randomimg cat="18,20,24" num="6" w="50" h="50" showlink="1"]
Shows 6 images from categories 18,20 and 24, 50×50 pixels and a link to each post the images belong to.

The shortcode can be used anywhere, even in a simple text widget for your sidebar or footer.

Installation

Extract the files into the thumbnails-anywhere directory
Upload the directory into your WordPress /wp-content/plugins/ directory
