Thanks drewish but i still have the problem. I went to Administer > Site configuration > File System and reset everything to default and I went to the image part as well but it's still not working. What next? I have even went on my hard drive and I've tried to remove the read only option but I just keeps turning on. I think I have a problem with my computer. Cause I've tried the image module before and it has worked properly. I'm running out of things to do so if you have another Idea please don't hesitate to tell me.

Thanks again for you reponse.
