Hi, I don't use php, but similar problems arise in Perl CGI, where
you can run a script as a user from a shell, but not from the web.

The problem is most likely a permissions problem, where your
web server is running with the absolute lowest permissions, and
it can't run things in /usr/local/bin. This is done, so that anyone coming
from the outside web, has no permissions except in specially defined
directories which are mode 777.  /usr/local/bin is probably 755

Check your web logs for errors. You probably can run convert from
the web server's cgi directory, but it all depends on the web server configuration
file.  You can also do things with "sudo" to allow the nobody:nogroup webserver
to run things, but it can be dangerous.

Thats my guess, :-)
