[Plugin: Custom Field Matrix] Show only if something is input

I want to make a grid that a user can fill in with an X. On the front end I want those table cells to show an icon/image only IF the cell has an X in it.

The problem I’m having now is I can get the X (text) to show no problem, I just want the <img etc etc /> to show instead, only IF there is an X in there. Ya dig? Any help?
