Get all custom image fields via API

[markus_blue_tomato]

How can I get from an image field all custom image fields dynamically?

E.g. $page->image->alt and $page->image->credits but how can I get this fields like $page->image->getCustomImagesFields or $page->image->getCustomImagesFieldsTemplate (where I can use the $template API methods $template->fields...

Ah - after describing the problem I found the solution quick

I'll check if there is a template with "field-" and current image field name.

$customImageFieldTemplate = wire('templates')->get("field-$fieldName");

After this I can iterate over $customImageFieldTemplate->fields
