Frequently Asked Questions (FAQ)

Pretty much just like an ACF Image Field. There’s a few differences, like not returning just an ID (there’s no point without positions), but the basics are the same. Make sure the Preview Size and Return Size are of a similar ratio. And make sure the image parent has a height. Image tag returns some additional markup on images: image alt The Image object now has a few more values too: 'focal_point' => array( 'class' => 'js-focal-point-image', 'top' => $value['top'], 'left' => $value['left'], 'right' => $value['right'], 'bottom' => $value['bottom'] ) 'class' refers to the class that Responsify.js is called on. This needs to be on the image tag to work. 'top', 'left', 'right' and `'bottom'` refer to the `data-focus` attributes used to control focal point. Build image as per above tag. Responsify is called on load and resize automatically on img.js-focal-point-image.
Make sure the image is wrapped inside an element that has a height and hasn’t had it’s overflow: hidden overridden (by !important). And that the image hasn’t had it’s max-width: none overridden.
Make sure the return image size (set when creating a Focal Point field) isn’t set to a small image size. Larger images work better.
Responsify.js tries it’s best to fit as much of the photo in the container as it can, whilst keeping the focal point a priority, and also keeping ratios correct. This means that at some sizes/ratios your image will be displayed too small for it’s container, try changing container size or image size. Or use background-size: cover.
Because for this to work, the image needs to move around within a container. Which means we need to hide the containers overflow. Which means we need to set a height. This is not made for wysiwyg style images, it’s for banners, sliders, fullpage, fixed height sections, etc.
Make sure that the preview size and the return size are the same ratio. It’s relatively accurate when they’re close, but for best results they should be the same. And make sure any image sizes aren’t differing their crops.
