In order to upload JPEG2000 (.jpf) images to a site I need to add a new mime type to config.php. What is the correct way to do this?

There is a configuration override you can use here:


Just use that in your config file to add your custom mime types to the whitelist.

  • When I add this I still get a File not allowed error: $config['mime_whitelist_additions'] = array('image/vnd.adobe.photoshop');

  • I doubt "image/vnd.adobe.photoshop" is the mime type for a JPEG2000 file. You'll have to look up the correct mime type string to white list.

  • Hence my question. I have not been able to find anything on that.

  • en.wikipedia.org/wiki/JPEG_2000 Right in the wiki page, image/jp2

  • Tried this: $config['mime_whitelist_additions'] = array('image/jp2'); Error persists.
