Image or icon on particular node output Is there any way to replace image/icon for a particular node output ?

A simple Example:

I am getting input from user sucn as 
"is your car running in petrol or diesel ?" if he selects the diesel then in node output instead of displaying diesel it should display the Diesel icon which i provide.

Is there any module for that because i have several input like this..Thanks
If your field is a reference field like node reference or term reference, then you can add an image field in the referenced entity for associating the image. Then in your node tpl file, you can load the referenced entity and print the image. If you do not want to write a custom tpl, then this can be done using the Display Suite module. But unless you need Display Suite for other purposes, the tpl way is better.
