This plugin adds a small counter to each image in your posts. It is convenient if you have 10 or more images in each post and people want to mention some of them in their comments. 
Now they can easily see the number of the image. 
The plugin doesn’t touch you database and doesn’t change your posts content it works as a filter “on the fly”.

So you’ve written some WordPress plugins and now you want to let your readers know about them?
The WP Download Counts plugin lets you do just that. It adds a sidebar widget which retrieves a list of your plugins and displays them along with the current download count (updated every 15 mins) and a link to each plugin’s listing in the WordPress Plugin Directory.
Features include:
<ul>
<li>Minimal configuration required – just a title and your WordPress username </li>
<li>Plugins listed in order of the most-downloaded first.</li>
<li>Plugin information cached for 15 minutes to minimize overhead</li>
</ul>
