Image upload error “Request Entity Too Large”

413 errors occur when the request body is larger than the server is configured to allow. Here’s how you can fix it, depending on your web server:

• Apache: Set the LimitRequestBody directive in either your httpd.conf file or a local .htaccess file. (https://stackoverflow.com/a/3719358/1688568)

• Nginx: Set the client_max_body_size directive in nginx.conf (http://www.cyberciti.biz/faq/linux-unix-bsd-nginx-413-request-entity-too-large/)

• IIS: Set the uploadreadaheadsize config setting (http://blogs.msdn.com/b/jiruss/archive/2007/04/13/http-413-request-entity-too-large-can-t-upload-large-files-using-iis6.aspx)

You also might want to try increasing PHP’s upload_max_filesize and post_max_size settings in php.ini or using the php_value directive in your .htaccess file if you’re using Apache (http://davidwalsh.name/php-values-htaccess).
