image upload in joomla

While I know this problem myself as I have hit it recently too, your lack of evidence showing that you have bothered to try answering this yourself says that you have just posted the question so that someone will do it for you. CP members are not paid to be here - search for it yourself, try something yourself, if you really can't get it to work, then ask on CP and tell us what you have done. Until then, no help will nor should come your way. I suggest you start on the Joomla.org site!
