Yep, that is easy as long as you are accepting and returning Stream and using WebHttpBinding. See Can a WCF REST endpoint be forced to accept Raw message format? and How to: Create a Service That Returns Arbitrary Data Using The WCF Web HTTP Programming Model

Basically as follows:

[WebInvoke(Method = "POST", UriTemplate = "processImage")]
public Stream ProcessImage(Stream inputImage)
{
    // do stuff with inputImage
    WebOperationContext.Current.OutgoingResponse.ContentType = "image/jpeg";
    return /* some stream with jpeg data */;
}

From the client, you are just posting an HTTP request. See Sending images using Http Post but use the resultant HttpResponse to access the returned image.
