I still use some old version of Paint Shop Pro version 8 (it is paid for)... does what little I know to do with photos (crop, size, and occasionally put in text). The newer opensource GIMP program does more but I didn't like the interface.
IMHO, anyone who doesn't make a living via computer art work would be unwise to monthly rent a software program. 10 dollars a month is still 120 dollars a year, that is crazy.
