<?php
    public function importFromPOST($tmpFile, $splitHeader = false, $publishPages = false, $chosenFolderID = null)

        $importer = Injector::inst()->create($importerClass, $fileDescriptor, $chosenFolderID);
        $content = $importer->import();

        if (is_array($content) && isset($content['error'])) {
            return $content;

        $tidy = new Tidy();

        $santiser->sanitise($htmlValue);

        // Load in the HTML
        $doc = $htmlValue->getDocument();

        $chosenFolder = ($this->chosenFolderID) ? DataObject::get_by_id(Folder::class, $this->chosenFolderID) : null;

The property chosenFolderID does not exist on SilverStripe\DocumentConverter\ImportField. Since you implemented __get, consider adding a @property annotation.

        $folderName = ($chosenFolder) ? '/' . $chosenFolder->Name : '';
        $imgs = $xpath->query('//img');
        for ($i = 0; $i < $imgs->length; $i++) {
            $img = $imgs->item($i);
            $originalPath = 'assets/' . $folderName . '/' . $img->getAttribute('src');
            $name = FileNameFilter::create()->filter(basename($originalPath));

            $image = Image::get()->filter([
                'Name' => $name,
                'ParentID' => (int)$chosenFolderID
            ])->first();
            if (!($image && $image->exists())) {
                $image = Image::create();
                $image->ParentID = (int)$chosenFolderID;
                $image->Name = $name;
                $image->write();
            }

            // make sure it's put in place correctly so Image record knows where it is.
            // e.g. in the case of underscores being renamed to dashes.
            @rename(Director::getAbsFile($originalPath), Director::getAbsFile($image->getFilename()));

It seems like you do not handle an error condition for rename(). This can introduce security issues, and is generally not recommended.

            $img->setAttribute('src', $image->getFilename());
        }

                        $node->parentNode->appendChild($parent);
                }
