Let me rephrase the first question. Being flash images, they don't suffer from pixelization when zoomed in. This means we can Zoom in the browser window to make the epicduel screen bigger, without compromising it's quality.
Taking a screenshot would get you, of course, a bigger image than the original size. I am asking if we can just represent part of that image, in a 900x600 size.
An example could be a zoom-in of the Meteor strike, or a zoom of the Core/upgrade menu.
...Or must it be an image showing the FULL screen?
