Resize animated gif images doesn't work properly #97

I'm trying to resize animated gif files without success. The patch consist to use the -coalesce option into imagemagick comand (this works when i call manually).

I think it can be used as a option into styles to not apply the -coalesce filter into images what aren't needed. Like:

has_attached_file :image, :styles => { :thumb => ['100x100#', 'coalesce'] }

I don't know if have a better way to do it, but this is a really needed feature

yes we need that... any progress?

I think you can resolve this by making your own processor. One of the problem we're currently have is that we use [0] to prevent some problem with pdf file. This would break any animated graphic file, and I think we're seeing a fix as pull request right now. I'm going to merge that in soon, and hopefully that will fix your problem.

Thank you for reporting in, I'm really appreciate it. :)
