It does, but the Slack servers still need to download the image first to know it’s size. There’s no equivalent for a browser. You could rely on Content-Length headers but then ad servers are just going to stop sending them.
- rietta 6y agoThis is Google though. It would seem that they could update Googlebot to penalize bypassing behaviors, lowering SERPS for any property that did such shenanigans. Or giving users in Chrome a Report Button that then filtered into site rankings.

Or download up to 4mb and if there's more then ignore it and just pull the first frame from the 4mb. Or if the content-length isn't set then assume it's over 4mb and only download the first frame. Granted there's extra complexity in parsing the first frame from a gif in real time.
