I have followed exactly the code here: [Convert HTML into PDF using Python](https://stackoverflow.com/questions/7584546/convert-html-into-pdf-using-python/7584674#7584674), but my images are still not showing up. They have absolute URLs, in any case.

xhtml2pdf and reportlab are both placed in my app folder as modules, so no import errors pop up or anything. The PDF renders fine, except that images are not being displayed. I tried to remove HTML and CSS width/height attributes as well to no avail.

Any pointers?
