Here's the setup:
Drupal 7 and Views 3.
Articles may or may not have images associated with them. On my home page, there is a block that has a leading article with image and then a list of articles next to it (all within a particular category). See screenshot below.
Since not all articles have images, I split this up between two views. The one on the left with the image has a filter that ensures I have an article with an image. It picks the single latest one. The view on the right is just a straight pull of the latest 7 articles.
There is a chance, of course, that one of the latest 7 articles has an image, in which case it'd be duplicated on the right. I want to, in the right list-only view, exclude the node listed on the left. I've been googling all morning, and have come up empty. I've dabbled with Views PHP but it doesn't seem to be working.
