Sorry in advance guys if the answer is obvious, I was kind of on the fence about this.

So I'm using a pre-made WP theme for my site, and it has an option in the settings to place an ad on the front page among the latest posts. My concern is whether this would violate the adsense terms. Whereas the actual posts on the front page have a picture, border (showing the category the post falls under), title, and snippet of text underneath, the ad is of course, just an image. Since the option was available in the theme, I was initially assuming this would be ok, but after seeing it implemented I'm wondering if it's skirting the line. Am I better off using a different provider for these types of ads or does this seem ok? I can add a picture of how this all looks if it would help people.
