<h3>Important note</h3>
<p>This plugin uses “Session Buffering” to work with some websites (for forcing replacement of titles). This means that if your host / web server uses a cache service there is a possibility that a conflict might occur. We give no support regarding host / web server support to avoid this.</p>
<h3>Planned changes</h3>
<p>In the future we plan to change the backend overview and settings page so it will use WP Table structure instead for better handling.</p>

It assumes that the theme's screenshot is in .png format. For smaller file size reason, I prefer using .jpg images for my theme's screenshots.

To set the record straight, .png is the preferred format, although other image formats are allowed. This is a direct quote from the Codex pages:

"Note that optionally, .jpg, .jpeg, and .gif are also valid extensions and file formats for the screenshot (though not recommended)." 

Other than that, this plugin is refreshingly small in size, and that's a good thing.

Almost there!
