Abstract: System and methods for uploading media content in an instant messaging application are disclosed. In some implementations, a method includes, at a first electronic device having one or more processors and memory: obtaining a request by a first user to associate a media content item with a conversation between the first user and a second user. The conversation includes a message and one or more responses to the message. In some implementations, the method also includes, responsive to the request: (i) causing a thumbnail of the media content item to be displayed in-line in the conversation; and (ii) causing the media content item to be display to the second user, in response to a predefined user action by the second user. The thumbnail is displayed in a first resolution; and the media content item is displayed in a second resolution that is different than the first resolution.

Abstract: A receiving from a first client a thumbnail of content selected by the user of the first client. The server provides the thumbnail to a second client and while providing the thumbnail to the second client, the server receives the content from the first client. After providing the thumbnail to the second client, the server receives an access request from the second client for the content. In response to receiving the access request the server provides the content to the second client. In some embodiments, the server sends a prioritization request to the first client to increase the priority of uploading the content in response to a request to access the content by a second client, and the uploading priority of the content at the first client is increased based on the prioritization request.
