How to "mark" only one image

[ank]

Hi everybody,
i am looking for a way to "mark" only one image in a imagesfield with multiple images, so i can request it on the homepage.

I am making a collection of pages with images and on the home page i want to display one image out of every childpage (not the first image of every child)

"I have been thinking on a switch next to the images so that i can "mark" the image, only one image in the imagesfield can be "marked"

 

Any ideas how to archive this ?

1. Enable tags in your image field
2. Set predefined tag "homepage".
3. Get urls of marked images

$pages = wire('pages')->find('myImageField.tags=homepage');
foreach ($pages as $page) {
    echo $page->myImageField->get('tags=homepage')->url;
}
