Hey!
No problem, I’ll be more than glad to tell you more about it! ??
The thing is, some WordPress’s themes have the option to set several different featured images, which disables our plugin to spot the right image to use it as a thumbnail. This can cause a lot of trouble for our users, since headers or banners can “infiltrate” in their thumbnails.
Custom field option is here to the rescue. Here’s how:
First, go to the create-new-post page or — even better — in one of your previously-already-published-posts. On the top right corner you should see the ‘Screen Options’ button; click on it for the drop-down menu to open. After that, tick the box next to ‘Custom Fields’.
Now you should be able to see a new box below the editor called ‘Custom Fields’. Create new custom field, name your image that you would later like to use it as a thumbnail for this specific post (something like “Featured thumbnail”), enter the URL of the image you would like to use and finish with the click on the button ‘Add Custom Field’. Of course, don’t forget to save this draft, or publish the post when you’re ready.
After that, visit the settings of (y)our plugin and scroll down to the bottom. The option called “Use custom field for thumbnails” should now be available, tick the box next to it, and select the value you’ve set up before.
Now, the important thing is this: the value of the Custom Field stays the same for every new post, while the URL of the image (obviously) changes. In other words: the name of the Custom Field stays the same, images change. That’s because once you set up your settings in the plugin settings (when you choose which value our the Custom Field our plugin should use for the thumbnails), you won’t have to change it again in the future.
Once you have set this up, you just add a Custom Field with every new post, set the image you want to use for the thumbnail, while the name stays the same. Also worth noting is that you should keep the images you want to use for thumbnails as square as possible and that they’re not too big. The perfect size would be 150×150 pixels, but that is not that crucial. Just don’t use the biggest images you can find, because this can return you some problems.
Sorry for this long, too-long response and please?— do not hesitate to get back to me if anything was unclear or if you have any kind of additional questions. I’m here to help!
Take care & have a nice day!
Best,
Silvo
