                if (extractor.viewMode === 'origin-download') {
                    imageURL = await image.CheckOnline(imageURL)
                    //imageURL = await image.loadAsBlob(imageURL)
                }
            } catch {
                console.log(imageURL)
                image.markAsBroken(link)
                link.setAttribute('target', '_blank')
            }

CheckOnline(url) {
            return new Promise((resolve, reject) => {
                let timer = setTimeout(() => resolve(url), 5000);
                GM_xmlhttpRequest({
                    method: "GET",
                    url: url,
                    headers: { referer: url, origin: url },
                    responseType: 'blob',
                    onload: function(resp) {
                        resolve(window.URL.createObjectURL(resp.response))
                    },
                    onerror: function(error) {
                        reject(error);
