Here are some tools I ran acrossed this am that may help with those who want a picture shrunk some for possibly a avatar or Signature Line etc...
Here is how you do that with the FREE
Irfanview viewer program:
After you install the program:
File - Open
navigate to the photo you want...lets call it horse.jpg for this example.
Highlight horse.jpg click OK
At the bottom of the window you will see the size of the jpg in pixels and kb (640 x 480 150kb/450kb)
The first kb is the file size (150kb).
Click Image - Resize/Resample
In the width box, change the width to the one you desire (say 200 for this exercise).
Click File - Save As
change the name to horse200
navigate to where you want to store the file.
LOOK down and find the "Options" button.
You will find a quality slider that goes from 0 to 100.
Move the slider to 50 and click OK.
Click File - Open
Look to the bottom of the window and find the new photo and file size.
If the file size is not small enough, do another "Save As" - Options button and move the quality slider even lower.
Or if you have WinXp, you can install the Power Toys Add-on Pak:
