Embed images to PDF without using HTML

How do I add images to the PDF without using a link or base64 string ?

```
byte[] bytArr = oHelper.GetImageFromFirebase(imgUrl, false);
```

The reason why link is not available is because its not globally available - only on localhost.

No base64 string because the size becomes huge since there are about 100 images.

So I am looking for a way to add images in the middle of the HTML page like we can do in mPDF - `$mpdf->Image();`
