Four-wave-mixing in hot atomic vapor is a versatile tool for spatially multimode squeezed light generation. We demonstrate multimode behavior for different pump-probe configurations producing either single beam squeezing or twin beams. To illustrate the usefulness of such fields, we perform an imaging experiment with two quantum correlated vacuum (squeezed) beams, where the spatially multimode character of squeezing is used to reconstruct an arbitrarily chosen pattern.
