On my single posts I have a full-width photo and some description of the photo. I need to insert a like “License this photo” as a caption of the photo automatically on every post. Is it possible to achieve? Please help!
Maybe the easiest solution is to create a re-usable block, so add your image block and give it a caption with the link in the block editor. Then click the 3 dot menu on the block toolbar and select Add to Reusable Blocks. Save it with a name.
Then whenever you create a new post, add that Reusable Block, click the 3 dot menu to convert it to regular block and update the image.
