I'd like to create a customized image (banner) to put at the bottom of the screen like this sketch I did:



How can I do that?

Jarredja is this a plugin? I mean like the combobox it has the swf file?
I inserted your code and nothing appears :(

I should have said that my custom img is a "banner" that would be displayed all across the bottom of my tour. I don't want single color. This banner would be totally customized... So my banner png has an width of 2000px.
I created the img and put it at the folder, but not shows up :(

alpha="1"
x="0"
y="0"
height="10%"
width="100%"

/>
