Firefox Does not skin your Titlebar. One reason I am still with ie. The other reason is Firefox is not as quick navigating as ie.
Ok go to that link that I gave you, click browse and find the image in your files. Then click on "host it". At the bottom of the page you will find a "direct link". Forget all the other ones. Copy that link. Now go this forum, click on the image button. When that box pops up, paste your link. "OK" "submit". There it is.
