Post Block is adding any image in post as featured image when none is set

[User]

Hey there!

I’m currently testing out the plugin via the free version.

Something I noticed is that when using the Blog Posts block, if you have no featured image set on a post, the block will pull the first image found in the post and use that as the featured image when doing Layout: Full post in the block’s settings.

Is there anyway to disable that?

I basically wanted the newsletter to show a post’s title, date, full content, and the FI *only* if there was one. Which 100% works when you just have a post with text and no FI set.

However, the posts I’m having this issue with have a thumbnail gallery (standard WP block) and no FI set and it’s pulling the very first image in the gallery as the FI.
The other one I tested, just has a image inside the post lower down after some text content and again no FI set and it’s doing it there too.

I really don’t want to have to use like a small transparent png for the FI in those cases to bypass this. Is there maybe a setting I’m missing?

Hi, the plugin does not pull the first gallery image, unless the constant

NEWSLETTER_USE_POST_GALLERY

is defined in the wp-config.php of your site OR you have a plugin autowiring the featured images when missing.

So I took a look at my wp-config and that wasn’t listed there. It’s also not a plugin since it’s a bare bones test site with just TNP activated. I’m also just using the 2025 theme that comes with WP installations. Could it be the theme then?

Hi, my fault. The Posts block uses a different image extraction function; I need to fix it to respect the NEWSLETTER_USE_POST_GALLERY or have an option to select the desired behavior.
On Monday I can work on it.

Thank you so much! I know it’s probably a very niche situation when using the posts block, but I really appreciate you looking into it Stefano. Have a great weekend!

Hi, on version 9.2.4, in the Newsletter/Newsletters/Settings (where one can add the custom CSS to newsletters), you should see two option to disable the featured image extraction from the gallery and the post content.

Hey Stefano! I just updated the plugin and unticked those new settings. Then I re-added the post block to my draft newsletter and it’s working perfectly! Thanks again for taking the time to look into this and also making the adjustments.

Hi Michael!

I’m still in the process of testing out the plugin (it’s actually going to be used by a client of mine if all goes well). And honestly, even if they don’t end up going with it, I’m absolutely coming back to give a review for you guys. You’ve been great!

[Michael]

That’s so nice to hear, thanks!
