  Colossal magnetoresistive (CMR) La$_{0.7}$Sr$_{0.3}$MnO$_{3}$ (LSMO) thin
films have been grown under tensile strains on (100)-SrTiO$_{3}$ substrates and
compressive strains on (100)-LaAlO$_{3}$ and (110)-NdGaO$_{3}$ substrates by
pulsed laser deposition.
  Using magnetic force microscopy (MFM), a "feather-like" magnetic pattern,
characteristic of films with an in-plane magnetization, is observed for films
deposited on both SrTiO$_{3}$ and NdGaO$_{3}$ while a "bubble" magnetic
pattern, typical of films with an out-of plane magnetization, is recorded for
LaAlO$_{3}$. We show that the shape of the magnetic pattern imaged by MFM is
fully correlated to the easy direction of the magnetization in the film.
