Inserting prompt into cookie
I am pretty new at jquery as well as javascript in general.. I am having a hard time figuring out how to prompt a user then save that prompt into a cookie.. I am wanting to make a option on my forum to have someone open a prompt enter an image url then save that url into a cookie as well as writing their response into a img tag to make it a background.. I already have a script to save backgrounds images but was wanting an option to allow my users to pick there own favorite image.. Dont know if this is the right place to be asking and thanks for any help anyone can give..
