How to test if this is empty::

<p><img src="[[commerce.get_product? &product=[[+tv.products]] &field=image]]" /></p>
This is inside a chunk, i would like to test if it’s empty.
I also tried setting placeholders within the getResources call onto the page to have [[!+product_info.image]]
but none of the tests I tried with this worked either…

This was cross-posted to the MODX forum where it has some different solutions:
