Resizing first makes compression less necessary. Compression is the reduction of file size by reducing the QUALITY of the image.
If you don't resize the image first, to compress a large (2 megabyte) image to under 200kb, it will have horrible artifacts and look terrible. Not only that, people will have to scroll left and right and up and down to see the whole image.
Resizing it to 800px wide first ensures that a) it will fit on people's screens without scrolling, and b) very little compression is needed to get it under 200kb - sometimes no compression is needed.
If you use irfanview (it's a free download) then you can set the amount of compression - more compression to get a smaller file size, less to get a larger file size.
Unfortunately it is trial and error unless there's a plugin for it that shows the file size, but you get to know how much is required. Even if it's 100kb that's fine - as long as it's under 200kb and when you look at the image it looks fine to you.
VSO Image Resizer is brilliant and it's what I use most of the time for just taking simple large size jpegs and resizing them to 800x600 for web posting.
The result is always under 200kb.
