Adding images text or symbols to a colored cover in trello?

[Rob Burdine]

I have peeked around here a little and cannot seem to find an answer to this. Maybe it is not possible yet. 

How can I take a colored cover and add text, symbols or images to it? Is this possible if so how do I get them into an editor like Snagit to modify them with say a Stop Sign or an SOS in bold text so I can alert those who can help me with a trello ticket?
