Any will help, I appreciate your time.

Select the publications you would like to submit to, request their Photographer's Guidelines, and follow them. 

Professional presentation is a MUST.  Be wary.  Art Directors and Photo Editors of magazines are completely jaded.  They see hundreds, if not thousands of images every single day.

Always remember your images will be sitting on a light table next to hundreds of other Photographer's images.  Make sure they're good before you send, or you will burn your bridge.

Good luck -

Yeah, what he said. Getting your foot in the door with editors is tough. It took me almost 2 years of submitting photos before I started getting editorial work. Now, if i get an assignment it's all editorial. I don't send in on spec anymore.

If you get in with writers it helps as well. They can have their stories submitted with your photos.
