I think the largest PNG file that I've been aware of was under 500KB.
I'm sure i've seen bigger.
A 1080p frame in uncompressed RGB is about 6MB. Afaict PNG gets of the order of a 3x ratio on photographic data so we are probablly talking a couple of megs of png if someone lifts a frame from a 1080p video.
You should be able to download that in less than 1/6th of a second with 24mb.
Unfortunately the intenet architecture doesn't handle short connections well. The TCP/IP stack doesn't know what the available bandwidth is so it has to be conservative initially. On high bandwidth but also high latency connections (e.g. user in europe, server in the USA or vice-versa) it often doesn't reach the full speed available before the transfer is over.
I just took a screenshot of my dual-monitor desktop and it was about 125KB. And that's just saving it with MS-Paint
This is pretty meaningless without knowing what was on the desktop at the time.
