I was wondering how to change my photo to 200k in photoshop. For some reason my older photos that I shoot with my Canon 40D won't upload after I just change it to 640 by 500

what I do is I adjust the resolution 200 DPI then change the size to 700 pixels wide, save as JPEG and then photoshop asks you to adjust the size before saving and just slide the thing down from 12 usually to 10 will put it below 200kbs....
In the Save for Web dialog, there's a little icon in the upper right hand corner. The kind of icon has varied across PS versions; in CS5 it's a little list icon. If you click on it, and fill in 200 in the Optimize for File Size box, and PS will do the size adjustment work for you. I don't think it matters what DPI you set; PS automatically drops the JPEG to 80 DPI.
-- Add any or all borders, signatures, watermarks you'd like to
-- Convert your photo to sRGB if it's in another color space
-- Resize your photo to the desired dimensions (NPN allows up to 720 pixels on the long side)
-- Save as a JPG and adjust the quality setting to get the file size small enough
The Save for Web feature simply does a good job of the last two steps, and is easier for some people (it also strips out meta data and the color profile by default, which can help in getting a higher quality, smaller file size).

As for the DPI, well, it has absolutely no bearing on the file size.
