WordPress Logo Still Displays after Logo Image PlugIn Install and Activation

Hi, I have successfully installed and activated the Login Image plugin Version 1.0.9.1.

I then go to Settings >> Login Image and then using the Browse button I find the logo image (png format) and click the upload button.

However under the statement “This is the image that is displayed on the login page (wp-login.php).” nothing is displayed and also on the Login page there is still the WP logo displayed.

* I have tried uploading png and jpg versions of the logo image using the specified image sizes of 310px wide and 70px height.

* Also deactivated and activated the plugin.

* Version 1.0.9.1 of the plug-in being used

Any help or suggestions would be appreciated, thanks.
