Avoid to send huge images (especially if you're not in hybrid mode).<br />
You can drag the slider to compress the image before it is sent (the original image is not modified). The file size is shown on the right. You can see the result in the image frame when you release the handle. <br />
Note: This does not include the overhead of the RS-encoding. </p>
