This powerful plugin allows you to insert HTML/Javascript code into your WordPress post’s content in a variety of different ways.
Using this plugin, you can specify pre-defined HTML code to be displayed at the top and bottom of all your posts, saving you valuable time. Merge fields let you pre-define HTML/Javascript that you can use anywhere in your post. For example, using [my_twitter] you can include an HTML link to your twitter account, anywhere in your WordPress post.

Display “Badges” in the side-panel which points to a web-site and an image which is then used to build the “badge”.
To access the configuration you have to go to Appearance > Widgets and edit the settings in the Panel.
Using the Widget you can choose whether to:
<ol>
<li>(Optionally) display a Title</li>
<li>Link to a site</li>
<li>Required link to an image to mark that site (any size will work, but the “standard” seems to be 88 pixels wide by 31 pixels high)</li>
<li>Pad the Badge (including centring the text); some people may prefer using their own CSS, so this is an optional configuration.</li>
<li>Enable “Display Badge in a Box” (enabled by default)</li>
<li>Enable the Displaying of a Drop-Shadow</li>
</ol>
If more control is needed, or more badges need to be displayed, the <a href="https://wordpress.org/extend/plugins/badges/" title="Wordpress Plugin" rel="ugc">badges plugin</a> on the WordPress site might be a better fit.

Badge

Display a badge (based the "badges") without requiring file-system access or knowledge of HTML.
