# Breaking: #68303 - Make tt_content imagewidth/imageheight nullable {#breaking-68303-1743324411}

See [forge#68303](https://forge.typo3.org/issues/68303)

## Description {#description}

The default values of the fields `imagewidth` and `imageheight` in the
`tt_content` table are now set to `null`.

This change removes the awkward UI behavior where the fields were previously
set to `0` when no value was entered.

## Impact {#impact}

Custom queries might fail if they expect the fields to be `0` instead of `null`.

## Affected installations {#affected-installations}

TYPO3 installations that rely on the `imagewidth` and `imageheight` fields of the
`tt_content` table always being integers are affected.

## Migration {#migration}

Use the "Media fields zero to null" upgrade wizard to update existing field values.

Also, modify your queries to handle `null` values instead of `0`.
