This is part of it.
18. Images should not exceed 200 kilobytes nor should they exceed 1024 pixels on the horizontal side or 800 pixels on the vertical side.

I know that but a vertical image would be 800 horizontal side and 1020 vertical side. so how do we overcome that constraint for a pure vertical image?
I am not sure what program you are using but I use CS4 or CS5 and when I put in 800 for the vertical side the horizontal can be anything as long as it is less than 1024. Depending on how you cropped it, but mine usually come out around 500-600 or so pixels.
