Keyword scanning shouldn't resolve images, unless they're using OCR to read any text they have. In that case, they'd be wasting a lot of resources.

Where do you get that this is using images?

Honey Docs doesn't actually explain what the callback looks like in the doc file, but it doesn't look like it has anything to do with images.

The HTML, DOC, and XLS files all have identical structure (though different content). They are all HTML, and Honey Docs is relying on Word/excel's parsing the HTML in those files to fetch the image (a 1px gif).

I downloaded the credit card Honeydoc. The content looks like:

    <html>Nicole  Davis  4556062729618215<br />
    Brian  Baker  4556767839126624<br />
    Patrick  Jones  4916615717158539<br />
    ....
    <br>
    <br>
    <br>
    ....

    </html>

Oh, and FTR, Excel gives a warning before opening the file. So they at least have thought through this vector (if you want to call it that).
