Hey @anonamix,
The shortcode has an undocumented parameter called thumbnail_build that can be used to have it list predefined thumbnails instead of WPP ones. I don’t recall the exact reason why it’s undocumented though (probably because there are some use cases where it won’t work as expected? It’s been a while since I last touched that part of the code) so keep that in mind.
To use it, you need to also make sure that:
- You define the width (in pixels) of the thumbnail with thumbnail_width, and it needs to match the width of your predefined thumbnail
- You define the height (in pixels) of the thumbnail with thumbnail_height, and it needs to match the height of your predefined thumbnail
- You set the thumbnail_build parameter with ‘predefined’ as its value
So, let’s imagine that you have a predefined image size called article_thumbnail and that its dimensions are 100px x 75px. Your shortcode then should look something like this:
[wpp thumbnail_build='predefined' thumbnail_width=100 thumbnail_height=75]
Of course, check your theme’s code to find the actual size you want to use and adjust the shortcode accordingly.
If you have any comments / questions please let me know.
