I looked at that link and I thought it was kind of vag so I went through the process of how to resize pictures in XP.
First go to start and then find Microsoft Photo Editor you might have to go to All Programs if you dont use it much.
Next after you are in the program go to File > Open then browse for you picture, and then click open.
After it is open go to Image > Resize and click it.
After that screen is open go to Units and select Pixels
Now you can resize it to the Max of 500 X 150 Pixels. Just make sure that it is within the criteria of the LS1tech policy.
For this one I had to do it 290 X 150 just so it was smalle enough. Click OK and now you are done.
Now all you have to do is upload it to the Photobucket or whatever you choose to use. Then post the url, with the [img] tags on each side, in your signature. Below is what my final product looks like.
