I can't post a code sample, but I'll give you the overview
for JPEG (since it's pretty easy as JPEG is a native PDF image
format) using the low level Cos calls (since that's how I like to

* Create a new dictionary (that will become your XObject)
* Add all appropriate values to the dict (Type, Subtype, etc.)
NOTE: it may be necessary to parse the JPEG data in order to
determine such things as BitsPerComponent and ColorSpace, unless you
already know this in advance)
* Create a new stream to hold the image data
specifying the newly created dictionary as it's dict, of course
* Add the stream to the page's resource dictionary
-- at point the image is in the PDF file, BUT it won't display - that's next
* Create a string that contains the content of the content stream
(q 1 0 0 1 x y cm /imageName /Do Q)
* Create another dictionary (for the new content stream)
* Add an attribute of the length of the content string
* Create a stream and copy the content string into it

That's it!
