Linking to the image in question would help.

When you upload a large image, a thumbnail is shown on the file page - which should be indicated directly under the image.

In most cases, thumbnails of animated images are not animated, but if you want to use the full size image, you still can.

In most cases, you should use full sized animated images in articles to avoid potential issues due to automatic resizing of thumbnails. If you want to use a smaller version, it's best to resize the animation yourself before uploading.
