Uploading .ISO files

[eluser]vonshavingcream[/eluser]
I have an uploadloader form working with the upload library. All is working except I can't get .iso files to upload.

I keep getting 'The filetype you are attempting to upload is not allowed.'

I updated the mimes.php file to include

Code:

$mimes = array( 'hqx' => 'application/mac-binhex40',
       'iso' =>  array('application/iso-image','application/octet-stream'),
    'cpt' => 'application/mac-compactpro', ...

But I still get the same error. It is not a file size issue, if I compress the iso into a .zip wrapper the file uploads with no issues.

Thanks in advance.
