Solutions

1. Ensure the divisor (usually an aspect-ratio denominator derived from width or height) is not zero before the division
2. Guard calls that compute ratios with a check for zero dimensions, e.g. if ($height === 0)
3. Use the library's resize helpers which handle degenerate dimensions instead of computing ratios manually
