You can upload a JPG, GIF, PNG, WAV, MP3, 3GP, or MP4 file. If you would like to upload an MP4 (video) file it is important to make sure that the size of it is no larger than 5MB. It’s often best to send links to video files as larger files attached to messages will not be sent. MMS files can be chosen from our royalty free Shutterstock image library, photos or video taken by a mobile device, or files uploaded from your computer.
