Modding Cross Fire's kill marks...[SOLVED]

Even though its about modding it still should be in the help section right?

Anyways... I made kill marks for my Cross Fire and tested them out in my game.
It didn't go as I planned... Well.. The image was too big to fit the size.. either that or it just doesn't like my pictures. When I get a kill nothing shows on the screen. Is there any possible way that I can EXPAND the size of the kill marks' threshold? or atleast solve my disappearing image problem?

1. This is the help section. You're in the right place

2. I guess you should refer to the killmarks/mods section to see what they have.

I actually don't know much about modding so you should have a more knowledgeable person coming soon.
