It is my understanding that you can do any thing you want to an
image, as any loss occurs only when you save the file. So if you
keep the original and only play with a copy you will never loose
anything.

That's true, but my inclination was to rotate and save the pictures that
need it when I'm home, then when I show the pictures to someone else
they will already be rotated and he won't have to wait while I fumble
with each one.

But when I tried this with Photo Viewer, it overlaid the first file.

One of the other two, Irfan or Fastsone, had a separate option to save
the photo separately. I might do that for each one (scattered through
1200 pictures) but if there is no point in saving the original, that
would be simpler.

That's true, but Irfanview can do a couple of permanent operations,
specifically rotation and cropping, without having to resave the
original JPG and thereby losing a generation of quality.

In a previous message there was talk about slide shows. Irvanview
can do slide shows easily.

You can even save them as a self-contained executable. With music even!

You just reminded me I had a viewer (or something) with music and I
haven't seen it for years. I really liked the melody too, but I can't
remember what its name was or even what it did (in case it wasn't a
viewer)..

There are actually two parts of Irfanview. The one is the normal
editing viewing window. There is a second part, Irvanview
Thumbnails. It can be added as as second icon, or access from the
Irfanview program.

The Thumbnail feature is good for a few things. You can choose various
pictures from the thumbs and then do a batch operation (rename,
convert, move, resize, etc.) and you can make actual discrete thumbnail
images for use on a web page.

It can do a lot of things. I felt, and feel, overwhelmed, by still
another piece of software.



The thumbnails part presents thumbnails of the folder access
like the
old light boxes. When you click on a thumbnail it opens the file
in Irfanview. In Irfanview Thumbnail you can manipulate the file
as if you were in Windows File Explorer.

I do not use Irfanview Thumbnail as it is just as easy to use File
Explorer, and set it for large thumbnails.
