image not appear in pdf – html2pdf

My Image tag:

 <img src="http://codeskulptor-demos.commondatastorage.googleapis.com/GalaxyInvaders/back07.jpg"/>

And my html2pdf code:

 html2pdf(this.$refs.document, {
          margin: 0.2,
          filename: "invoice.pdf",
          pagebreak: { after: ".sautDePage" },
          image: {
            type: "jpeg",
            quality: 0.98,
          },
          html2canvas: {
            scale: 1,
          },
          jsPDF: {
            unit: "in",
            format: "letter",
            orientation: "portrait",
          },
        });

Please give me any idea because now my image not display inside pdf. It is visible on page but not in pdf.
