my friend just gave me her old camera, and i tried using it but the photos are much too large when i put them on the computer. 3072 x 2304. is there i way i can make them smaller?

i dunno much about cameras, ive never had one before. i says fujifilm finepix z on the front if that makes any difference.

Open them on microsoft office paint manager (the orange one) and select 'resize'
