Adding author avatars to your SEBLOD list items isn't immediately obvious, but can be achieved dynamically with the Select Dynamic field and a little bit of SQL Query code. I've stepped through these instructions below to make it easy for you. This is a neat feature to add if you want to give the authors of different content items in your search results some added prominence.

STEP 1: Open the Content Type of the Content you are listing (it is important that you do this in the content type so it is locked to this content type)

STEP 2: Create a new field that is a "select dynamic"

STEP 3: Change the Query to "free"

STEP 4: Enter the following code

SELECT b.avatar AS text, a.id AS value
FROM #__users AS a
LEFT JOIN #__cck_store_form_users AS b ON b.id = a.id

STEP 5: Make sure the storage is Standard > Article > created_by

STEP 6: Save your field.

STEP 7: Add your field to the view you want the Avatar to display on (Content, Item or List).

STEP 8: Apply the "HTML" typography and write the HTML code - remember to replace my_field with your actual field name:

< img src="/$cck->getText('my_field')" alt="Author Avatar" />
