Where exactly must I use a credit? Its not clear.

I have a blog that hosts editorial content. When I use an image here, I will add the standard Adobe image credit.

I also have the main company website which has teasers that point to my blog post (on a different site.) The teasers consist of image + headline + 2 sentences explaining what the article is about. It clicks through to the main content on the blog site.

The Adobe guidelines for photographer credit are:

We require a photo credit to be added only when using the image in an editorial article or for social media.

My company website is not an editorial article (it is a teaser that points to an editorial article) and it's not social media. Do I need to add an image credit, or will the image credit on the article itself suffice?
