You don't submit photos; the photographer does. So what you need to do is work with photographers that actively get published or at least are regularly submitting work (assuming their work is good enough for the intended magazine).

I'd also like to add that anything you do for submission purposes can't go on the internet or be published anywhere else while it's being considered for submission so be prepared for that aspect of it since the delay between the time you submit and finding out whether they were accepted can vary greatly.
