Pictureino

Imaginator is built on the per-breakpoint aspect-ratio idea pioneered by EXT:pictureino (zeroseven/pictureino). The two extensions conflict by design as they register the same backend field. So they cannot run side by side:

Swap the package

composer remove zeroseven/pictureino
composer require schliesser/imaginator

No database migration

The aspect-ratio field is the unprefixed aspect_ratio column, the same column pictureino used, so existing editor data is preserved as-is. There is no schema change and no data migration to run.

Template changes

Replace the pictureino ViewHelper call with <i:image>. The per-breakpoint {alias: ratio} map keys resolve to the configured breakpoints, matching pictureino's behaviour:

Fluid template

<html xmlns:i="http://typo3.org/ns/Schliesser/Imaginator/ViewHelpers"
      data-namespace-typo3-fluid="true">

    <i:image image="{data.image}"
             aspectRatio="{data.aspect_ratio}"
             alt="{data.header}"/>
</html>

After swapping templates, review the configuration. The ladder, format and processor defaults differ from pictureino's.
