Increase the upload file size via php.ini

In some circumstances you may want to increase the maximum file size you can upload to WordPress.

You can do this using a php.ini file which goes in to your wp-admin directory. Using a text editor, create a file called php.ini and paste in the following, adjusting it to suit your upload needs;

memory_limit = 32M
upload_max_filesize = 24M
post_max_size = 32M

Save the file and upload it to your wp-admin directory and that's it!
