The image titles are showing on my home page. How do I remove them?

The content on the home page is set in the design skin:

Gutensite Control Panel --> Content --> Design --> Customize Design --> Modules

There are usually 2-4 Module Areas available, depending on which design skin is in use.  Scroll down to the Module Area that contains the Image Button entry. 

1. Edit.
2. Change to the Settings tab.
3. Toggle "Display Image Title" to "Hide".
4. Save.
