Here is what worked for me. Please note that I hard-coded the name of our images folder, rather than taking the time to create an options field where you could indicate the images folder input field [recommended]. You may need to modify that to match yours.

// new function to validate url for image to import
function woocommerce_osc_validate_url($url){
		$ch = curl_init($url);
		$opts = array(CURLOPT_RETURNTRANSFER => true, // do not output to browser
			  CURLOPT_URL => $url,            // set URL
			  CURLOPT_NOBODY => true, 		  // do a HEAD request only
			  CURLOPT_TIMEOUT => 5);   // set timeout
		curl_setopt_array($ch, $opts); 

		$retval = curl_exec($ch); // do it!
		if ($retval !== FALSE){
			$code = curl_getinfo($ch, CURLINFO_HTTP_CODE);
			$retval = ($code == 200 ? TRUE : FALSE); // check if HTTP OK
			curl_close($ch); // close handle
		} // END IF
		return $retval;
	}

// modified the import_image function to use the CURL validator above
function woocommerce_osc_import_image($url){
		$attach_id = 0;
		$wp_upload_dir = wp_upload_dir();

		$filename = $wp_upload_dir['path'].'/'.basename($url);

		if(file_exists($filename)) $url = $filename;
// checking two folders because some fool stuffed some of our images in each
               // first look in default /img/ folder.
		$enc_url = rtrim($_POST['store_url'],'/').'/img/'.rawurlencode(basename($url));
              // if not found, look in /images/ folder
		if (woocommerce_osc_validate_url($enc_url)===FALSE)
			$enc_url = rtrim($_POST['store_url'],'/').'/images/'.rawurlencode(basename($url));

               // using CURL again, to copy file, for efficiency and to detect success/failure
		$fp = fopen($filename,'w');
		$ch = curl_init($enc_url);
		curl_setopt($ch, CURLOPT_FILE, $fp);

		$data = curl_exec($ch);

		curl_close($ch);
		fclose($fp);

// only create attachment information if the file copied successfully
		if ( $data === TRUE){ // the file copied correctly
			$wp_filetype = wp_check_filetype(basename($filename), null );

			$attachment = array(
			'guid' => $wp_upload_dir['url'] . '/' . basename( $filename ),
			'post_mime_type' => $wp_filetype['type'],
			'post_title' => preg_replace('/\.[^.]+$/', '', basename($filename)),
			'post_content' => '',
			'post_status' => 'inherit'
			);
                        // Not sure why '37' but it is working, so I'll leave it...
			$attach_id = wp_insert_attachment( $attachment, $filename, 37 );
			require_once(ABSPATH . 'wp-admin/includes/image.php');
			$attach_data = wp_generate_attachment_metadata( $attach_id, $filename );
			wp_update_attachment_metadata( $attach_id, $attach_data );
		}
		return $attach_id;
	}

Hope this helps!

Added the following code to the listSubscribe() function in CC_SuperClass. This allows me to add to my lists, rather than replacing them:

// Check if email already exists; update if it does
 if($existingID = self::CC_Contact()->subscriberExists($params['email_address'])) {
//added next three lines to ensure our new selection adds to our subscribed lists, instead of replacing them...
	$contactDetails = self::CC_Contact()->getSubscriberDetails($params['email_address']);
	$contactLists = $contactDetails['lists'];
	$params["lists"] = array_unique(array_merge($contactLists, $params["lists"]));
//end of new code
            $contactXML = self::CC_Contact()->createContactXML((string)$existingID,$params);
