Wordpress file upload

Hi! I’ve got quick question I’ve seen on some wordpress theme great feature – upload button in Custom Panel. As far as I know how to do nice Custom Panel, and how to store data etc, I have no idea how I can use Wordpress uploader, and pass for example link to the file from it to theme options. I’ve searched google and codex, but without results. So maybe somebody have some info about it, or were to search? thanks

hey I actually bought a theme from onuro called Portfolious. When you are about to make a post, there’s an option below the textbox to upload an image and when its done, it gives you the image link. I wondered how to do this but you can probably contact onuro to find out.
