As some one pointed out already, the best way to resize pictures is to have a resizing tool. You may notice that most of the pictures shown here that
are "resized" are distorted. If you run XP get the Image Resizer
This is only part of the solution, also get the Power Calculator
from the same site. It's much easier to work with.
Now you need a formula to help you resize pictures accurately to proportion. Try this:
X is the desired width
W is the original width
H is the original height
Y is the proportional height.
Let's say you have a picture to use an an avatar and it's too wide: 200x300. An avatar can be only 160 pixels, so you use this formula, as entered
on the calculator:
Now you can enter those dimensions into the Image Resizer
Here's an example where a picture is too narrow:
Apply the formula using the Power Calculator
Enter 160 and 219 (always round down) into the Image Resizer
Notice that the Image Resizer
has taken care of the rounding error for you.
You can use the same formula with some adjustments to correct for height, as well.
I hope this helps.
