To enable a theme, click
If the theme has never been enabled on this site, you will have to check the "enable" box and then click the "Save configuration" button at the bottom.
To set up how the theme works, click on the "Configure" link (not the tab at the top).
Fill in the fields.
Save the configuration.
Don't leave the page yet.
Logo and favorite icon
Now use that "Configure" tab
Some people prefer to do this part under the "Global Settings" but it can be done theme-by-theme.
The "Default Logo" is that little picture (usually) in the upper left corner of the page. For example, on the "Bluemarine" theme, it's the Drupal logo.
If you want to change it, here's how:
- First, find out what size it is because you'll want your own logo to be about the same. (If you are comfortable with HTML and CSS, you can also edit the theme's code to accommodate your logo rather than resizing the image. How to edit theme code is not covered in this guide.)
- Under "Logo image settings" either type in the path to your logo, or upload it from your PC.
- Note: Neither one of those options turns off the "Use default logo" check box. You must select the correct check box yourself.
- The "Shortcut icon" (a.k.a. the favorite icon, or "favicon.ico") is the same way. If you want to change this, you must specifically say, "Hey, Drupal, I'm changing this."
Now you click the "Save configuration" button. If you did this in "Global settings" it affects all themes (assuming they behave properly); if you did it for a single theme, then only that theme is changed.

HINT: Going to make a few (or a lot) of changes to a standard theme? Think about copying it over to your
/sites/sitename/themes/ folder and renaming it. Then you can do anything you want and still be able to undo it easily by recopying. If the changes are a bit bigger, think about contributing it back to the community (with your name, of course).
