Quickly output a 404 for static files that aren’t found, rather than loading the normal 404 page.
Any static files ( images, text, pdfs, etc ) that don’t exist will 404 as soon as possible, rather than loading the entire WordPress application.
<h3>Details</h3>
By default, the list of extensions to check are the results of <code>wp_get_ext_types</code>, but can be filtered with <code>static_404_extensions</code>.
The output is a static page with the text <code>404 Not Found</code>, this text can be edited by filtering <code>static_404_message</code>.
A 404 status code will be used, but can be filtered with <code>static_404_response_code</code>.
Passing true to <code>static_404_should_process_request</code> will short-circuit and skip processing the request. This filter gets passed the current request.

Hate when you get those ugly errors and warnings in your WordPress admin area (especially when WP_DEBUG is turned on)? 
WP Admin Error Handler sorts that out by catching all the errors and warnings and displaying them neatly in the admin bar 
so you can read them at your convenience.

WP Admin Error Handler

Taming WordPress and PHP errors and displaying them properly.
