Faststone Photo Resizer 3.0The software I use for "Re-Sizing" photos is
"Faststone Photo Resizer",
It does a quality job, and many options. It can batch rename without resizing also. It allows you to adjust just about
any size you want though the "Advanced Options/Re-size" tab. It also allows you add text (Copyright notice) and borders.
Best of all it is FREE!
The next series of images are how to a do a simple re-size without text or a border.
----------------------------------------------------------------------------------
This is the opening screen, the left side are your photos on your computer, in your specified folder.
The right side is where all your setting are. along with the photo you picked in the upper portion.
You will notice that one image is has a blue border around it, that is the chosen image to be re-sized.

-----------------------------------------------------------------------------------

To add that image, click on the "ADD" tab, and the file will be added to the re-size window.
-----------------------------------------------------------------------------------

After you added the image (s), go to the "Settings" tap, and click on it.
Here you will find various setting for quality, adjust to what you want,
(Remember that you can save your Thumb Nail in many file types, I have JPG chosen)
Click "OK"when you are done here.
The setting I have set are for the best IQ with embedded EXIF.
------------------------------------------------------------------------------------

The next thing you do, is pick a folder to save it in. You can made a new folder or sub-folder at this time,
if you want to save them in a separate folder.
-------------------------------------------------------------------------------------

Next is the "Advanced Opens" tab.
Here you have lot of option tabs, But, click on the "Resize" tab. Be sure to "Check" the check box to activate this tabs options.
You have a few options here to resize by, I usually pick "Based on one side".
Next you can use the drop down menu and pick a side for resizing. I usally pick size for the "long side",
Which may be either the Vert or horz side.
NEXT: pick the number of pixels you want the "Long Side" to be with the next drop down menu.
You can also punch in an exact number if you want or need to.
--------------------------------------------------------------------------------------

Here you can see a preview of your new image, click on the small preview logo (as highlighted) to view.
you can also see the before and after size (highlighted)
And you scrool through all the images you are re-sizing by clicking on the arrows.
--------------------------------------------------------------------------------------

Before you convert the file (s), you can rename them with anything you want as a prefix.
I added "800LS-*" witch will put "800LS-" in front of the real file name.
If you want to change the whole file name, don't put the "*" at the end.
You also have a drop down menu for other options, including renumbering and date fields.
Make sure you check all the options here, (4 check boxes). Plus the Preview box...
especially, the "Ask to Over-right", just in case, you forget to put them in a new sub-folder, and forgot to adjust the rename field.
When you ready, click on the "Convert" button.
--------------------------------------------------------------------------------------

The pop up screen will list all the files, and show you the progress.
When it is done, It will say "DONE" on the button at the bottom of the screen.
Click on "Done" at this time...
Your finished.
