I've made a time animation in Pro that I have exported as a GIF.
(I was originally planning on making a time slider web app but when I shared my time enabled layer the layer would come through empty).
I tried to put the GIF into the Storymap using the image tool, however it is greater than 20mb.
I also tried publishing this to Google Photos and using the URL from that to embed as either a video or website, however "This website doesn't support inline embedding"
Does anyone have any suggestions on what else I can use to get the GIF into the storymap? I have no idea where to go from here.
20 Mb is a big GIF. It might be worth converting it into an MP4 or MOV file and uploading it to YouTube or host it yourself.
Hope this helps,
