I kept getting all kinds of errors because the installer wants the parameter:

allow_url_include = off

set in the php.ini file. I have discovered that I have to put a copy of this php.ini file in several different places to allow the script to work properly, for example, in the main directory, in the admin directory, and now, to solve this particular problem, in the "simg" directory. By putting a copy of the php.ini in this directory, it solved this problem for me, and the image file see more is now loading properly
