it’s a post i haven’t put up yet, but i’m wondering what the tricks are here. i’ve already tried deleting the image link and deleting everything in the size fields, although the current post only has the image link deleted.
Take a close look at that link that you posted above. It’s still 2011. Are you referring to a scheduled post that has yet to be published?
Did you fail to set your date and time zone up here > Settings > General?
Animated gifs will not operate unless you presize them to the exact size required prior to uploading them into a post or page. If you do not so that the cropper comes into play they will not work. Have you deleted the image from your Media Library as well as from the post? If so then the next step is to presize the animated gif and upload it.
