How to get the value of a variable in CCK from Devel? I am using a custom .tpl file to theme teasers, and I am having trouble with the value of a variable returning true even when apparently there is no value inside ($picture). I would like to see what exactly this variable contains.

How do I leverage Devel to view this variable without having to var_dump()? Currently, the teasers are inside a view which is inside a block on the home page.
As you mentioned after enabling the Dev module, you can use dpm($variable); to get a detailed graphical listing of the array values.
