under pressure seeking shortcuts (aren't we all), has anyone got a PHP
method for calculating estimated download time for files?
I've got a load of images and I want to warn about possible lengthy
downloads in a friendly way.
Failing a ready made script, can anyone point me to a resource that
gives a good estimate of download times per kb for a range of common
connection methods?
It strikes me as weird that I can easily find the obscure information by
a quick google search, but find it impossible to uncover what ought to
be simple stuff...

If you want to code in PHP then you can get the file size and divide it by
known connection speeds. So if you have a file that is 86Kb;
28Kbps connection - 3.07 seconds
33Kbps connection - 2.61 seconds
etc.
So really there is just some quick math involved, along with the knowledge
that connection speed is not absolute. A 28K connection may not really be
28K at all.
HTH!
