In order to determine reliable constraints on the upper part of the IMF in very young embedded super-star clusters we have undertaken high spatial resolution mid-IR imaging and spectroscopy of young starburst galaxies with TIMMI2 on the ESO 3.6 m. Results on the prototypical starburst NGC5253 are presented here using detailed photoionisation models to reproduce a large number of observables including mid-IR to radio observations at various spatial resolutions.
