If you click on the layer then press Ctrl + T you should be able to change the size and rotation of layer.
The answer depends on what you want. The entire image or a single layer reduced. Former is Image>Image size (or crop tool). The latter, Curt Y already stated.
Also after I hve one picture open, if I open another the first disappears, why?
Might you be unfamiliar with tabs?
Photoshop > Preferences > Interface > Open Documents as Tabs
Photoshop > Preferences > Interface > Enable Floating Document Window Docking
I only have used PSP3 and 4, they are so much easier. I just make pictures for a site called Glitter-Graphics.
When I hit the crop tool, it made my picture 10 times bigger? I know about layers in psp. I open one, then open
another to add to the first one, etc., when I'm all done I merge visible.. I just need to learn the basis on Photoshop.
Guess looking for online tutorials is my only hope and most of those I can't understand, I'm 56 and have carpal
tunnel and arthritis, this keeps my hands working.Thanks

Check the settings in the Options Bar before commiting the Crop.
