The registration page of a PHPFox website is presenting a world map image. However, the concept of representing that the community is world-wide may not match your actual needs.
If you want to change that image to a custom one, which is related to the actual purpose of your PHPFox community, there is an easy way for achieving that.
Log into your cPanel account and locate the File section. Then, simply click on the File Manager service.
Access the location of your PHPFox website. In our case, this is the public_html/ directory. Then, you need to navigate to:
Rename the file called banner.png to something else.
Click on the Upload button at the top menu and then upload the image that you wish to place on the registration page of your website. Make sure that it is using the same name: banner.png
All done! When you access the front-end of your website, you will be able to see the new image placed properly.
