No, I am coding the PDF document from scratch using VB.

        Oh, the hard way!

I have been able to add text, and graphics such as lines and rectangles, but I havent been able to figure out how to add an image

        Image are tough - not because of the PDF file format, but because you will need to support parsing each image file format into a generalized "bitmap" and then putting those bits into the PDF correctly.

My main concern is how is the image objects organised?

In which object do I specify the image that must appear on a page? In the page's resource dictionary, i specify the object that hods the pages' content in a stream, such as text. However, if I add the image object to the contents array, all i get is a grey page?

        You create an XObject of /Subtype /Image.  You add that to the /Resources of each /Page that uses it.

        Then inside the content stream of each page, you just use the /Do operator.
