The issue here is that the user wanted to check if a repeating field has any empty values.
Solution:
This can be done by using the code below.
[wpv-for-each field="wpcf-my-field"]
[wpv-conditional if="'[types field='my-field'][/types]' ne '' "]
Content goes here if field is NOT empty
[/wpv-conditional]
[/wpv-for-each]
What the above code will do is to loop through each index of the field then with the conditional checking if that index is empty. Finally replace "wpcf-my-field" with the slug of your image field keeping the wpcf- prefix EXCEPT when it is being called in the types shortcode.
Problem: I see a Fatal Error related to the Heading Block when using Toolset Blocks:
Fatal error: Class ToolsetBlocksBlockStyleBlockHeading contains 1 abstract method and must therefore be declared abstract or implement the remaining methods (ToolsetCommonEsBlockStyleBlockAPartlyWithConfig::print_base_css) in /path/to/site/wp-content/plugins/toolset-blocks/vendor/toolset/blocks/server/Block/Style/Block/Heading.php on line 13
Solution: Update Wordpress and Toolset to the latest versions.
