Conditional display of CCK fields I was wondering if there is any other way apart from coding (and, possibly, using the rules module) to make the showing of a field dependent on the existance of another field.
Say you have in a node, a video and a photo. You want to show only the video in teaser but if you have not provided a value for the video, then the video field should not be showing, and instead the photo field should be showing. 
If you have provided a video, then the photo field should not be showing.
Any ideas?
The only solutions I know except coding it by yourself its Content Templates module. This module allows you to change the template directly from you back office.

The advantage it's that you don't need to deploy your code if you need small change. 

You've also Display Suite that seems promising, I never tried but the description sounds good for what you need.
