One common template change is to use your own graphic/image. Simple graphics (not banners) are linked in the html file. Simply change the reference to the image of your choice in the html file of your template. In the adminsitrative interface do this by going to Site =>Template manager and then selecting your template. Click the icon for html.

Keep in mind that it if it is a different size than the original image this may change the appearance of the site in unexpected ways.

Additional information:

The images for a given template are generally located in this folder:
/templates/templatename/images (Substitute the name of the template you are using in place of "templatename").

A trick for finding the name of the image is to put your cursor over it and click right. Select view image. This will display the image and give its full url. Sometimes the images are background images. This is viewable in Firefox or you can look for the background tag in your page source.

How to upload an image:

There are many ways to upload images. Which one you use will depend on your host and server.
1. You can use an ftp client.
2. You can use a cpanel file manager.
3. You can use the media manager.
4. You can use various extensions that allow uploading, including joomlaexplorer and galleries. 

The page that contains the link you click on to load the wrapped content is the parent page.
You can get out of the wrapper by clicking on anyone of the links in the menu of the parent page.
If there are no other menu items visible then the wrapper may have been loaded directly into the parent page, replacing the content that was initially there.
This however defeats the purpose of having a wrapper which is a means of simply enclosing content from another site within the parent site. 

A Mambot is a small, task-oriented function that intercepts content before it is displayed and manipulates it in some way. Joomla! provides a number of Mambots in the core distribution, e.g. WYSIWYG editors, but there are many other mambots available for specific tasks.
Some 3rd Party developer components have their own mambots which need to be installed in order to make the component work properly. In Joomla! 1.5 mambots will be renamed plugins.
Plugins: The new name for mambots. In addition, some 3rd party components, modules and mambots themselves have plugins. 

Joomla! is released under the GPL (Gnu General Public License 2). 

At any given time you may see a padlock next to a specific item in Joomla!'s administrative backend. These padlocks may be displayed next to any of the following (Content Items, Menu Items, Modules, etc).

The Joomla! system places these padlocks next an item to indicate that a user is currently editing (checked out) the item. The lock is removed by the sytem when the user clicks on the "Save" button for that item.
If the user never clicks save and instead hits the "Back" button or naviagtes to another page, then the item stays locked. If another user needs to work with the item he or she must have the item checked back in before the can work.

There are two ways of checking items back in. One way is to contact the person that has the module checked out to see if they are done with the item.

The other option utilizes the administrative back end;
Click on "System => Global check in"
This option should be used very carefully, especially in multi-user environments. This single action checks in all previously checked out items, whether they were checked out by you or not. Possible undesirable side effects may be that multiple editors end up working on the same document.
In this case who ever clicks the save button last has their version saved as the final copy.
