Bitrix: Transferring images of catalog sections from one site to another

I describe the solution to the problem of transferring images from one site to another. Provided that in both cases the CODE sections match, and for sections on the source site that do not have an image specified, you need to get it from any product with an image included in the section.

Getting a list of sections with images in json format

  require_once ($ _ SERVER ['DOCUMENT_ROOT']. '/ bitrix / modules / main / include / prolog_before.php');

if (! CModule :: IncludeModule ("catalog")) {die ();}


$ arFilter = [
    'IBLOCK_ID' => 17,
    'IBLOCK_TYPE' => '1c_catalog',
    // 'ACTIVE' => 'Y'
];

$ arSelect = [
    "ID", "NAME", "CODE", "PICTURE", "PREVIEW_PICTURE", "DETAIL_PICTURE", "SECTION_PAGE_URL"
];

// Get a list of information block sections
$ sections = CIBlockSection :: GetTreeList ($ arFilter, $ arSelect);

while ($ ar_dep = $ sections-> GetNext ())
{
    if (! empty ($ ar_dep ['PICTURE']) ||! empty ($ ar_dep ['DETAIL_PICTURE'])) {
// If the section has an image
        $ result [$ ar_dep ['CODE']] = $ ar_dep;

        $ img = $ ar_dep ['PICTURE']? $ ar_dep ['PICTURE']: $ ar_dep ['DETAIL_PICTURE'];

        $ result [$ ar_dep ['CODE']] ['SRC'] = CFile :: GetPath ($ img);

    } else {

        We get the last product in the right section
        $ elementIterator = \ Bitrix \ Iblock \ ElementTable :: getList ([
            'select' => [
                "ID", "NAME", "PREVIEW_PICTURE", "DETAIL_PICTURE", "IBLOCK_SECTION_ID", "CODE",
            ],
            'filter' => [
                '= IBLOCK_ID' => 17,
                '= IBLOCK_SECTION_ID' => $ ar_dep ['ID'],
                '= ACTIVE' => 'Y',
                '! = DETAIL_PICTURE' => '',
            ],
            'order' => ['ID' => 'DESC'], // sorting
            'limit' => 1,
        ]);

        $ elems = $ elementIterator-> fetchAll ();

// If a product is found in the section, then write the src of images
        foreach ($ elems as $ element) {
            $ result [$ ar_dep ['CODE']] = $ ar_dep;

        }

        if (! isset ($ result [$ ar_dep ['CODE']] ['SRC'])) {
// We are looking for the first available product included in this section or any subsection of this section
            $ rsResult = CIBlockElement :: GetList (
