I would like to say a couple of things. When people hear "stock images" they assume it's about ...stock photos, the ones you download for free on websites like Pexels or Shutterstock. And we live in times where people often read just the title of an article. So, I suggest you consider a name change.
The idea to use "stock images" in the title as a requirement, also is not the best option in my humble opinion. Sure it can help the discovery of the posts but it also creates a false impression that these are low quality posts. The title should always be unique and hashtags be used instead.
