This small update fixes the resolution change to work with anything up to 800x600 and removes the button "Half Size image(320x240)" as that can now be done with camera controls and removes the button "Single image"(as this was becoming hard to keep control of) and adds the new button "Extra Tile Distance" which adds an extra row of distance to the exporter.

The extra tile row cannot be tested or cropped. I will see about added an extra tile distance soon.
Thanks to Skitnik for the suggestions, Keep them coming and I will keep adding them ;)
