Do I have to change that and the htaccess file where tc_ is mentioned?

Also I've found out the problem with my images not loading with rewrite on, it's only the background images for some reason, other images load fine. Any idea's

Before I forget the module less part...... whats it for? is it to remove the tinycontent dir and modules dir in the url???
if it was that would be GREAT :) and if so how do you use it lol

Thanks for bearing with me on the replys too GIJOE
