hi, i have seen all the upload progress bar plugins , widgets, etc. they all suck. their either too bulky with too much useless code or they dont work. what i want to know is where can i read up on how to display an easy upload progress indicator. most browsers have a status progress bar on them below but it isnt very professional to use just that when dealing with clients. how does the browser do it? i want to know the internals of how the browser work with indication a status of something uploading and maybe i can make something using php & jquery.

thanks
