General Support: No images of any kind, not even button graphics

Hi,

I just installed plogger on my HostMonster account - it was not difficult, and it seemed like everything was going smoothly. At the point where the installation was completed, and the initial admin login was accomplished, the pages lost all their graphics, tab images, buttons, etc., and showed only text links for everything. The system continues to appear as if it is functioning, but no images of any sort.

I believe this is a result of my changing the "Gallery URL:" parameter before realizing that doing so was a mistake. Can someone tell me what that value should actually be (again)? In the format: http://domainname/plogger/????? (/plogger is my install directory).
