You can insert a picture in the animated .gif format and it will show up in the mailing. Just drop them in to an image placeholder as you would any other image. One caution is that you can't make any edits to the animated gif once it is uploaded. This means you can't resize the picture or change the file name. Make sure you have the gif exactly right prior to uploading, and you should be just fine. Another thing to note is that some mail programs won't render the animation and may only display the static image. If you need any other help, just let us know!
