The standard location that Joomla uses to store images is /images/stories. If you don't like this, you can change it:
- Login to Administrator as demonstrated in lesson 6 of our free Joomla tutorial and go to Global Configuration
- Click on the System link
- Next to Path to Image Folder enter the location you would like to use; for example a lot of people prefer to use just images
- Click Save in the top right
WARNING: do not delete or rename the /images/stories folder on your hosting account. It is used elsewhere and if Joomla can't find it, you may experience some errors.
