@ chaddng. Thanks for posting. My module does not provide any feature that allows the article to be edited. So, I really don’t know to what you are referring. To set the limit to 30MB, all you do is calculate the number of bytes: 30 x 1024 x 1024 = 31457280. Note that there are 1024 bytes in 1 kilobyte and there are 1024 kilobytes in 1 megabyte.
However, please bear in mind that regardless of what you specify in the module fort he maximum file size, this value is limited by the upload_max_filesize and post_max_size values in your PHP settings.
