Location directive context is *server*, not http:

Cf. http://wiki.nginx.org/HttpCoreModule#location

Why are you compressing already compressed image formats like JPEG and
PNG? Seems to me like a waste of CPU cycles.

Also you can use:

gzip_disable "msie6" 

Cf. http://wiki.nginx.org/HttpGzipModule#gzip_disable
