The file does not appear to be an image. Bug? I've installed the latest ImageMagick on my ubuntu 14 server. If I force imageDriver to use 'imagick', I can only upload Gif images. And if I force it to use GD, I can upload all images but only static gif images.



The images are not changed in any programs.

It's important for me to have both options. Any ideas what this issues can be? I use php 7.0 

Upload failed for background.jpg. The error message was: “Error uploading the file: The file “/var/www/html/craftcms/craft/storage/runtime/temp/assets57cb93709cf445.74590720.jpg” does not appear to be an image.”
That error will occur if the fileinfo extension or imagick (ImageMagick) extension are not configured with a comprehensive list of file MIME types (the "magic file", as they refer to it, I think), or the images you're uploading aren't really images despite their extensions.

Regarding GIFs - you must use ImageMagick if you want to upload animated GIFs, as it's not possible for Craft to reconstruct an animated gif using the GD library.
