Suppose I am serving a web page to a gwt client app. The web page
html, at various places, has unique string segments which the client
app will recognize. The client app should replace the strings with
images on the rendered page, just as if the html had <img> tags.
Except the images already reside in the client app as Image instances
and I don't want to fetch the images from the server.

I expect I will need to use JSNI and document.write, or something like
that. I am not experienced with Javascript, so I have some learning to
do.

Has anyone done something like this: a client app inserting its own
images into a page?

Thanks,
Bob Woodbury
