This disclosure details the implementation of apparatuses, methods, and systems for a portable, image-processing transmitter. The transmitter provides a platform capable of managing, manipulating, storing, and transmitting digital media files across a wide array of transmission means and protocols. In one embodiment, the transmitter may be employed by photographers, photojournalists, and/or the like to rapidly process, edit, and send photographs or video to multiple news agencies, newspapers, magazines, television studios, websites, and/or the like while maintaining control over their photographs by allowing them to send reduced quality and watermarked proofs. The transmitter may be configured to allow users to first generate and transmit low-resolution preview images, thereby saving on transmission time and resources, and only send full resolution versions once approvals of the preview versions are received. The transmitter's broad communication capabilities ensure that it is maximally effective in locating and exploiting available communication networks, even from remote locations.
