What type icon can use for conditional formatting
I have an icon on my layout that I can use conditional format to hide it if one is not signed on as an admin. I am not sure the icon type. I have tried putting other icons on the layout that I need to hide but when I choose conditional formatting it doesn't allow me to access that option. What type of icon should I use? I have tried .png, .ico, .jpeg. None allows conditional formatting option.
