Gallery2 server path

I was wondering if its possible to add a directory outside of the installed path. For instance I have gallery2 installed under the username maytas and gallery2 is installed in (using fake names for privacy reasons)

Say for instance I create a new username called uploader and I want to add that to my server path for images or whatever is it possible to do?

I was able to add /home/maytas/ but i want to add /home/uploader/uploads

is this possible?
