Manipulating images

[Ian Reid]

After a recent group seaborne holiday I have received a CD containing 
hundreds of photos, all stored in landscape format. I want to select 
a number for a file on my 5500/250, using OS8.1, to show to rellies 
and friends and therefore need to be able to rotate those in portrait 
format by 90 degrees.

Versiontracker.com provides an extensive list  of possible software 
but I need guidance in choosing. I am talking home viewing, not 
professional multi-media presentation. Can somebody please help.
