Reducing to this size will not lower quality of the "computer" viewed picture. Make sure when you reduce the dpi, that you also increase the pixels as programs tend to compensate by making it smaller. I use about 800 pixels wide and proportionally long.
As another method, you can use photobucket, I believe this site will automatically make your pics web friendly as well as act as an image host for them.

I second the votes for hosting on photobucket. Not perfect, but free and functional.
