i currently have a D50 and am considering upgrading. i am a freelance journalist who does a lot of travelling with my reporting (mainly in the Middle East and South America) and i want to be able to sell photographs from my travels to add an extra source of income (and enjoyment).
i started to use the D50 regularly about a year ago, and am now learning to manipulate aperture, shutter speed, ISO, manual focus etc, independently of the scene mode offerings. i typically shoot 2-3k images on a trip, and travel roughly every 3 months.
what i would like to know is first whether i am right in thinking i'd be well-advised to upgrade my camera body in order to increase the resolution, so i can produce a higher quality image / larger publishable image at 300dpi?
second - if i do need to upgrade, then how far do i need to go? i've looked at D90, D5000, D300s and D700 and found myself unable to determine which i need, given the combination of being at a relatively early point on the digital photography learning curve, but still wanting to produce publishable-quality images.
i only have basic lenses too, the 18-55mm kit lens and the AF-S Nikkor 55-200mm 4-5.6G.

Welcome to Nikonians! You might want to ask your publisher as to what they want to see regarding image file sizes and resolution. What works for a newspaper would not be acceptabe at National Geographic. Each has their own requirements. Your D50 may be all you need. Adding new glass will usually do more to increase Image Quality than replacing the camera body. Your subject and ambient conditions should be taken into account when choosing the best camera and lenses for your particular needs. Good Luck and Enjoy your Nikons!

you said that glass selection comes down to what i'm shooting - can you give me any more guidance? all i can tell you first off is that i'm not a sports/wildlife photographer, so won't be shooting fast moving objects!
