I only have remote access to my server so to view a png file I just copy it to my wwwroot :)
If this last part worked then your setup looks to be ok.

I am guessing that the include_path variable controls where MW will look for included PHP files, can you make sure that the path to texvc is in your apache user's path environment variable. (Note: I'm not sure how to do this for non-login users, I just created a symbolic link from /usr/local/bin - can anyone enlighten me?)

I believe if you change $wgScriptPath you'll also need to change $IP or MW_INSTALL_PATH - but I'm not too sure when it comes to moving an existing insallation. There's probably no milage in trying it imho.

So; check that texvc is in apache's path is the next thing.
