# Breaking: #102755 - Improved getImageResource functionality {#breaking-102755-1704381963}

See [forge#102755](https://forge.typo3.org/issues/102755)

## Description {#description}

The hook `$GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['tslib/class.tslib_content.php']['getImgResource']`
has been removed in favor of the new PSR-14 event
`\TYPO3\CMS\Frontend\ContentObject\Event\AfterImageResourceResolvedEvent`.

The new event is using the new `\TYPO3\CMS\Core\Imaging\ImageResource` DTO,
which allows an improved API as developers do no longer have to deal with
unnamed array keys but benefit from the object-oriented approach, using
corresponding getter and setter. Therefore, the return types of the following
methods have been changed to `?ImageResource`:

-   `\TYPO3\CMS\Frontend\Imaging\GifBuilder->gifBuild()`
-   `\TYPO3\CMS\Frontend\ContentObject\ContentObjectRenderer->getImgResource()`

## Impact {#impact}

Any registered hook implementation is not executed anymore
in TYPO3 v13.0+.

Calling the mentioned methods do now return either `null` or an instance
of the `ImageResource` DTO.

The new Event is also using the new DTO instead of an array.

## Affected Installations {#affected-installations}

TYPO3 installations with custom extensions using this hook or calling
mentioned methods directly.

## Migration {#migration}

The hook is removed without deprecation in order to allow extensions
to work with TYPO3 v12 (using the hook) and v13+ (using the new event)
when implementing the event as well without any further deprecations.
Use the [PSR-14 event](https://docs.typo3.org/permalink/changelog:feature-102755-1704381990)
to allow greater influence in the functionality.

Additionally, adjust your code to handle the new return types appropriately.
