[chromium-extensions] Re: How do I call "chrome-extension://[id]/image.gif" via a script?

Tue, 20 Oct 2009 12:44:54 -0700 

Still can't seem to get it to work. I tried Marcos' suggestion, but
instead of what I expect it to do, it tries to pull the page in
question + /image.gif. For example, if you're on google.com and you
expect to see the image, after inspecting the element, you will notice
the img src is http://google.com/image.pdf, instead of chrome-
extension://blahblahblah/image.pdf.

I've tried chrome.extension.getURL() in the same manner but that did
not work. It returns what I expect, but I can't use that in a css
selector like url(image.gif).

I am very appreciative of the answers thus far, but I'm afraid the
majority of you are speaking over my head. Jói, are you saying this
cannot be done in a user script?

I am not sure how else to phrase my question... if you have a user
script extension that uses an image, and you need to reference it
locally with css, how do you do it? If I use an image that is not
local, I can do it easily. I don't understand why it isn't trivial to
do the former and not the latter. If you wouldn't mind, please explain
it with an example of something that works. I'm just an amateur coder,
so I have a hard time deciphering suggestions like

something.here {
 do this
}

Thanks very much.
