I have tried shrinking the width/height but, I figure it has more to do with the KBs and I'm not good at editing around that stuff.
In the future, if you, or anyone here who reads this wants to make a change and use a new image for a Sig, but you're not sure if it's okay to use, just make a post here in HJU's SIG REVIEW THREAD (est. 2007, located in the HJU ART INSTITUTE subforum) -
http://forums.henshinjustice.net/showthread.php?t=16746 There is also the HJU SIG GUIDELINES THREAD, which outlines some basic guidelines about what HJU members can/can not have in their Sigs. It is located here (est. 2007, located in the SITE UPDATES AND ANNOUNCEMENTS subforum) -

The problem was obviously with the height of your image, not the filesize (or as you put it,
"the KBs"). You posted an image that exceeded the maximum height that is allowed for Sigs here at HJU.
Any image manipulating software like PhotoShop, GIMP, or even a basic one like IrfanView, can be used to adjust the height or width of any still image. For anyone who is inexperienced with manipulating images digitally on a computer, this process is also known as "resizing". You say you
"tried shrinking the width/height" of the image, your problem was that you just did not shrink it enough.
Here is what that image SHOULD look like when it is at the maximum allowed height of 165 pixels:
