Im = imread('Polar_Bear_With_MATLAB_Hat.png')
ImSz = size(Img); % Get Dimensions
DiagLen = hypot(ImSz(1), ImSz(2)) % Invoke Euclid To Get The Diagonal Length

Any size. The answer is in pixels, not real world units. For that, see my attached spatial calibration demo.

Square or rectangular only, but any size that can fit in your computer. Other shapes require the typical specific geometric metrics for them, but they are all still likely to be squares or rectangles originally, simply because that is how the majority of imaging devices format them.
