Does any one know of a reliable resource for Paint Shop Pro Tutorials?

I have an old version

PSP 7

And I need to know two things specifically at the moment

one how to split an image up into sections…so that they can be printed in those sections and put back together afterwards, making the image larger (like to make a really big stencil portrait)

also how to separate high mid and low tones when threshold-ing something (for making multi-layer stencils)

I am novice stencil artist and am in need of some information to help me hone and advance my art

thank you all for your help…Im sure what ever you can pull up will be of tremendous benefit to my practice…
