Excellent work again Beefeater. It's pretty easy to resize your images, depending on what program you have.

If you have any version of Photoshop, just open the screenshot in it and go to the Image menu, click "Resize" and then "Resize image". A dialogue box should pop up with the image dimensions. Edit the width from 1024 pixels (presuming your running the game at this resolution) to 790 pixels (standard width of most forums).

(Note that if the height & width are 'locked' [you'll see a little chain linking the height and width boxes] then the height will edit itself to scale with the new width. If not, you'll have to manually edit the height to 593 pixels to keep the image proportional).
