FileValidatorImage

This module implements ProcessWire’s FileValidator interface, which is used by

$sanitizer->validateFile() as part of ProcessWire’s built-in file validations. This is used by existing file uploads, for example. This module adds support for validation of common image bitmap formats: JPG, PNG, GIF.

$reason = $sanitizer->errors('last string clear');
echo "Image not valid because: $reason";

This is also useful if you want to specify min/max dimensions
$validator = $modules->get('FileValidatorImage');
