I think the root of the problem you are grappling with is that putting
an image on a page requires two http requests: one that creates an
image tag with the appropriate src attribute, and then the request
from the browser when it tries to display that img tag.
If that isn't acceptable then there is a way of encoding the image
data in the img tag your self, you basically stick
<img src="data:image/bla,base64encodedimagedatahere" />
It's not supported by all browsers though (

)
