Help with Images Path !

Hi Experts,

I am sure one of you came across this issue before and should be simple to solve:

Whenever I want include an image in one of my posts through Typolight is going to include a totally different URL:

[img]system/html/paris-84c6fb0b.jpg[/img]

Of course the image isn't located there and browser is not able to display it, actually the image is located:

tl_files/mytemplate/images/paris.jpg

What do I am doing wrong? or what I am missing?

Your help is greatly appreciated...
