# Important: Profile image keeps its own format where WebP is not allowed {#important-ace-848-academic-persons-edit}

## Description {#description}

The profile detail view of the `academicpersonsedit_profileediting` plugin
rendered every source of the profile image with `fileExtension: 'webp'`. The
image view helpers of TYPO3 throw for a file extension that
`$GLOBALS['TYPO3_CONF_VARS']['GFX']['imagefile_ext']` does not list:

```text
Unable to render image uri in "tt_content:1": The extension webp is not
specified in $GLOBALS['TYPO3_CONF_VARS']['GFX']['imagefile_ext'] as a valid
image file extension and can not be processed.
```

The default list of TYPO3 v12 does not contain `webp`, so on such an
installation every profile with an image failed to render.

The partial [`Resources/Private/Partials/Profile/Show/Image.html`](https://docs.typo3.org/m/typo3/reference-coreapi/main/en-us/ExtensionArchitecture/FileStructure/Resources/Private/Index.html#file-extension-resources-private-partials-somepartials-fluid-html) now asks
the new view helper `<pe:imageFileExtension preferred="webp" />` of the
namespace `FGTCLB\AcademicPersonsEdit\ViewHelpers` for the format. It returns
`webp` where the list contains it, and an empty string otherwise. Then TYPO3
picks the format as for any processed image: the format of the original file,
or PNG for a format a browser cannot show.

## Impact {#impact}

Nothing changes where the list contains `webp`, which is the default on
TYPO3 v13. On TYPO3 v12 without `webp` the profile image is rendered in its
own format, or as PNG, instead of failing.

## Affected Installations {#affected-installations}

Installations that override `Partials/Profile/Show/Image.html` of this
extension keep requesting WebP unconditionally. Replace `fileExtension: 'webp'`
there as the shipped partial does:

```html
<html xmlns:pe="http://typo3.org/ns/FGTCLB/AcademicPersonsEdit/ViewHelpers"
      data-namespace-typo3-fluid="true">

<f:variable name="fileExtension" value="{pe:imageFileExtension(preferred: 'webp')}" />
<img src="{f:uri.image(image: profile.image, maxWidth: 690, fileExtension: fileExtension)}" alt="">
```
