Error uploading .bmp file format - gets rejected

Question

I'm doing some testing on file uploads and discovered that the .bmp file format gets rejected even though defined in my config file as an allowed file extension.

I have added the following to my config file:

 'extraAllowedFileExtensions' => 'bmp, jpeg, tiff, pdf, cdr, gbr, gtl, dxf, dwg',
 'allowedFileExtensions' => 'bmp, jpeg, tiff, pdf, cdr, gbr, gtl, dxf, dwg',

This is the error I receive:

The file “/private/var/tmp/php7Md2bj” does not appear to be an image.

/shop/craft/app/etc/image/Image.php(138)

138    throw new Exception(Craft::t('The file “{path}” does not appear to be an image.', array('path' => $path)));

How do I fix this?

Answer 1

You're probably using GD, which doesn't support BMP files.

If you install Imagick on your server, Craft will use it automatically and it supports a much wider range of file types, including BMP files.
