Make sure you're looking at the math subdirectory in the upload dir 
('images' by default), not the top-level 'math' directory which 
contains the texvc source and executable.

If images/math doesn't exist yet, make sure that images is writable by 
the web server so that it can be created.

However if you're running in PHP's "safe mode", the directory must be 
_owned_ by the user that owns the scripts; if the scripts created the 
subdirectory then it is owned by the web server user instead and "safe 
mode" is sufficiently anal retentive that it won't let your scripts put 
anything else in it. In this case you probably need to create the 
images/math directory yourself, and make it writable to the web server.
