I don't know if this is due to limitations, but whenever I upload a gif with a transparent background it won't update the empty pixels. It will only reset once the gif has gone through it's cycle. Maybe add an exception in the image create command for uploading transparent gifs to force render empty pixels as well?

Yup, Yamipa does not support animated GIF files... yet.

Could you provide a sample GIF file I can use for testing? Looks like an interesting feature to add.

AWESOME. WORKS GREAT.

I just published a new release with support for animated transparent GIF files: v1.2.2
