Hi all!

anyone knows how to send a compressed jpg with the Net library?

I've tried to send a byte array and everything works, but actually i'm sending uncompressed data...

SERVER code here:

first run server sketch and then client

an image named "img.jpg" must be in server "data" folder to work

create a font named "f.vlw" and put it in server "data" folder

give focus to server window and press 's' to send the image to the client

THANKS!!! :)
