Systems and methods for image optimization

Abstract

Images are optimized to reduce latency prior to being transmitted to requesting client devices. A request from a client device for an image is analyzed to obtain the attributes of the requesting client device and the network used by the client device for transmitting the request. The parameters of the image to be transmitted are determined based on the attributes in order to reduce data latency at the requesting client device. A requested image that meets the parameters or which has its parameters preset by a provider can be transmitted without any changes. A requested image that does not meet the parameters is transformed in accordance with the parameters so that it is optimized for the combination of the network and the requesting client device.
