If you are using the most up to date config file then the issue is likely just one of having the correct paths specified in the globals file.
What happens when you attempt to upload an image? Do you see a blank place holder where the image should be? What is the browser you are using? If you use FireFox you should be able to right click on the image and view it's properties to see where it is expecting the image to be coming from. Most of the time this will be enough info to let you know what values you need to update to get the image to show correctly. You should also take a look to see if you have some extra new folders in your site, image userimages as all one word or anything like that. Please post back with what you discover.
