Is Photo Shop included in XP-Home?
no----you have to buy Photo Shop
No chance. That program runs from $300 to $600. How intense a program do you need? There is an abundance of free photo editing software available out there.
Irfanview has been around seemingly forever and upgraded as time passes. Be sure to grab the plug ins if you try this simpler program.
Photofiltre is a more intense program. I have read good reports on it.
Paint.net is also a good option program. NOTE, this is nothing to do with MS Paint.
There are lots of others, Google each to see which might suit your needs but remember the more intense your intentions the greater the learning curve.
