added

if( $arResult['MORE_PHOTO_COUNT'] = sizeof( $arResult["PROPERTIES"]["MORE_PHOTO"]["VALUE"] ) ) {
  $showSliderControls = true;
  foreach($arResult["PROPERTIES"]["MORE_PHOTO"]["VALUE"] as $FILE_ID) {
    if( is_array($FILE = CFile::GetFileArray($FILE_ID)) ) {
      array_push($actualItem["MORE_PHOTO"], $FILE);
    }
  }
}

immediately after the definition of $actualItem, everything is displayed, but the slider does not scroll. Maybe I went the wrong way?

Answer 1

My Crutch Recipe:
After

else
{
  $actualItem = $arResult;
  $showSliderControls = $arResult['MORE_PHOTO_COUNT'] > 1;
}

add

if( $arResult['MORE_PHOTO_COUNT'] = sizeof( $arResult["PROPERTIES"]["MORE_PHOTO"]["VALUE"] ) ) {
  $showSliderControls = true;
  foreach($arResult["PROPERTIES"]["MORE_PHOTO"]["VALUE"] as $FILE_ID) {
    if( is_array($FILE = CFile::GetFileArray($FILE_ID)) ) {
      array_push($actualItem["MORE_PHOTO"], $FILE);
    }
  }

  $arResult['MORE_PHOTO'] = $actualItem["MORE_PHOTO"];
  $arResult['MORE_PHOTO_COUNT'] = sizeof( $arResult['MORE_PHOTO'] );
}

Where

MORE_PHOTO ( $arResult["PROPERTIES"]["MORE_PHOTO"]["VALUE"] )

Property code with pictures.

Is the problem on the server side? If the slider does not scroll, you need to look in the browser console. Perhaps there are some JS errors.
