# Breaking: #92118 - TCA ctrl thumbnail setting dropped {#breaking-92118}

See [forge#92118](https://forge.typo3.org/issues/92118)

## Description {#description}

The TCA setting `$GLOBALS['TCA'][$aTableName]['ctrl']['thumbnail']` has been dropped.

## Impact {#impact}

Setting the control field for a custom table has no effect anymore.

## Affected Installations {#affected-installations}

The setting has been used in the **List** module for tables with image fields to render a preview
of attached images. It has been used for `tt_content` in core versions until TYPO3 v7.
There are probably not many extensions using the setting. The **List** module will
no longer show preview images for rendered rows.

## Migration {#migration}

Drop this setting during extension clean up. The setting is simply ignored, no PHP error will be thrown.
