Disclosed are media attachment systems to enable a user to embed a first media item with a link to a second media item, and distribute the first media item in a message to one or more recipient client devices. For example, the first media item may include a picture or video captured by a user at a client device. The user may generate a message that includes the first media item. In response, a media attachment system may cause display of an interface at the client device that includes an option to attach an address to a second media item to the message. For example, the second media item may include a web page, social media post, picture, or video identified by an address such as a Uniform Resource Locator (URL).
