The up graded edition of the Limited Edition of Photoshop 5.0 is available
direct from Adobe for $99.00. It likely can be bought on ebay for much less.
GO:
http://www.adobe.com/products/photoshople/main.html
I recommend it because the operations and use of its comprehensive tools are
intuitive do not require a lot of learning.
There are some pictures on this page which I think are quite nice.
http://www.landandseacollection.com/id38.html
They were taken with an Olympus D 400 rated at 1.3 MP, and edited with the
LE 5.0 Edition of Photoshop. They were saved at 3 on the JPEG Options scale
(histogram) which determines file size.
