This may sound silly, but for the life of me, I can't see how to change the extension's logo at chromeextensions.org. Does anybody here know how to do that?

Thanks!

did you include a screenshot to your extension ?

Yes, I have uploaded an image. I have an image up that I want to change. I've tried uploading the new image, re-organizing the media in the obtuse media manager, etc., but I just don't see a way to change the existing image that is displayed as the main graphic for the extension.
