Currently we only support JPG and PNG as output formats. It would be great if we could support GIF too. Unfortunately the support for resizing operations on animated GIFS is quite poor in ImageMagick.
We may look for an alternative library for handling GIFS specially but in the meantime it would be great to support a simple passthrough. If the input and output is GIF we just return (a redirect to) the original file. This would not be semantically correct but it would help greatly on projects where the same image field should support normal images and GIFs.
