Systems and methods for remotely viewing medical images on a client device having a zero-client web application with a buffering module. The zero-client web application receives an image series selection from a user and receives corresponding series details from a web server. The zero-client web application generates an off-screen image array according to the series details. The buffering module outputs image requests based on the series details to a web server. The web server is in communication with a medical image database storing images in a non-web browser compatible format (e.g., DICOM). The buffering module then populates the off-screen image array with converted medical images received from the web server. The zero-client web application further includes an on-screen image and a display module. The display module sequentially sets converted medical images of the off-screen array as the on-screen image to stream the converted medical images.
