Because this line.
https://github.com/humhub/humhub/blob/master/protected/modules_core/file/libs/ImageConverter.php#L299

This function " $exif = @exif_read_data($filename);" need php "php_exif" extenstion ".

First time when I have problem I don't know how to fix.
Recommend : It would be better if humhub include "php_exif" requirement in selftest admin page .

EXIF is part of default PHP environments. Only Windows users must enable extra DLLs for EXIF support. Thank you for the information.
