+gdImageArc (image, center point X, center point Y, diameter X, diameter Y, Angle start, angle end, color);
+Make sure the diameter X and Y are the same, as this makes a perfect circle
 ====DRAWING AN ELLIPSE====
+gdImageArc (image, center point X, center point Y, diameter X, diameter Y, Angle start, angle end, color);
+Make sure the diameter x and y are different integers, as this stretches the circle on the larger side making an ellipse.
