Hello SSl,
Thank you for your post.
You may have noticed when viewing the view page source of the phpbb3 login page there are two lines of code presented in reference to the logo/background. One is for larger screens (tablets and PCs) and the other is for cell phones. You will notice the target URL for cell phone sized screens has the word mobile in it;

And, a second thank you for including the image shot of the Header Banner screen and URL for support. As I stated at the very beginning of this posting, a second problem I have is in the ACP with module labeled Header Banner as it fails to launch when clicked. Please refer to the second post in this topic for the text of the error message I get when trying to launch the module. Now that you have included a screen shot of the module I can see it contains the URL pointing to the jpg image file.
I did try uploading the headerbanner folder with all sub folders from a backup to the server (after renaming the existing folder) but, it still gives the same error message. So it's off to support and see where it leads.
I'll post again with the solution of failure to launch of the Header Banner.
Finally, I was able to implement a back door temp solution so now the banner does display on larger screens. Although, I still have to find a solution to the Header Banner module not launching.
Can't thank you enough for your valued assistance. This last post you placed gives me the best opportunity to move forward.
