Developing a plugin for wordpress is really an awesome feeling. After you submit this to wordpress, it will be available on the plugins section and your plugin will be used worldwide. But the way this shows up in the plugins page is not that eye-catchy. So how come if we can provide some cool graphics (banner) over there so that user will have a better feeling accessing your plugins page. You can provide some message about you or your website using that banner. Here is a live implementation for my WTI Like Post plugin.
