👍 I can look at trying to integrate the example code at disintegration/imaging#23 but my go fu is not strong.

Since the bot asked...I can see why this feature may not be a priority but it is preventing me from updating to the newest version of hugo-academic ever since it started using image processing of header images (see linked issue). I really think animated images are an appealing feature for header images in blogs and other types of websites.

Yes, I have flagged this issue as "keep" and we will eventually get to it ...

Would it take a lot of work to fix this issue?

In my comment above (https://github.com/gohugoio/hugo/issues/5030#issuecomment-410286337) I think I'd found that it is just a case of doing some extra work around how animated images are processed - which was covered in the disintegration example file.

I've completely forgotten the details though so maybe it's more involved.

Probably not, but any feature will take at least "some hours" when you consider implementation + tests + docs.

I really wanted this, and took a stab at it. I am way too new to Go and hugo in general to get this working unfortunately, but any advice and pointing in the right direction would help

I am having trouble successfully getting the right io.Writer to use

This seems to be modifying the source image as well (the non resized version)

+1 to the requests for gifs to be supported as featured images for hugo-academic.
