Using Tiki6 from trunk with a pretty tracker for display...

How can I have a default value for an empty (null) field in a tracker item? Or better yet, how can I "skip" the empty field?

For example, in my tracker I have an optional field that a users can fill with the URL of their personal blog.

In my pretty tracker template I use:

{img src=img/wiki_up/blog_icon.png link="{$f_1}"}

This works great (gives me a stylized icon for the user's blog link) when the user has a blog. But since the tracker field is optional, some users don't a blog. In that case, I'd like to skip that entire section of the pretty tracker.

In psuedo-code, I want something like this:

if ($f_1 != "") the (
{img src=img/wiki_up/blog_icon.png link="{$f_1}"}
) else (
No blog
)

How would I achieve this result with Tiki's pretty trackers?
